Version 11.0.1

Works with

FileMaker Pro 14-18
FileMaker Server 14-18
Mac OS 10.10-10.14
Windows 7-10

Manipulate any information on your disk

Troi File Plug-in lets you deal efficiently with any files or folders outside the database. All from within FileMaker you can:

  • get data from files that are on the disk of the computer into FileMaker
  • create files anywhere on the hard disk and put data from FileMaker fields into them
  • manipulate files and folders on the disk: this includes creating, deleting, copying, moving and modifying files and folders
  • query detailed information of files and folders: the size on disk, creation and modification dates and much more
  • launch and reveal files directly from FileMaker
  • manage your images and movies: get images and their metadata (IPTC, Exif, GPS, XML) inside your FileMaker database and write IPTC and Exif metadata too!

80 functions and 38 script steps give you ample power

Troi File Plug-in adds 80 functions to FileMaker, giving you virtually limitless possibilities! Starting with FileMaker 16 plug-ins can also add script steps. In File Plug-in version 11 you will find 38 functions which perform an action as script steps. You can select these in the script steps pane in Script Workspace, or you can begin typing the script step name, then choose it from the list that appears. The script steps significantly expand the possible actions you can perform with FileMaker.
Here we give you just some examples of what you can do with this plug-in:

Manage your media

Troi File Plug-in allows you to retrieve extensive image and movie data like width, height and depth, and much more. While we were at it we also added an extensive example file ManageMedia.fmp12. This example file combines some of the Troi File Plug-in’s functions to create a powerful Media Manager for images and movies. It shows how to import one or multiple images and/or movies from a folder. It also retrieves a wealth of metadata like width and height, IPTC metadata (amongst others caption, description, keywords, copyright), GPS, XMP and Exif metadata. Exif metadata is information about the time a photo was taken, aperture, shutter speed and the like. And did we mention the example file also works with movie files?

Writing metadata

With Troi File Plug-in you can write EXIF and IPTC metadata information to your image files. By using the “-SetImageURL” switch you can set the Photoshop Image URL metadata (not part of the official IPTC specification). The “-UTF8CharSet” switch can be used together with the “-SetIPTC” and “-SetEXIF” switch. This will write the metadata encoded as UTF-8 text and will set the CodedCharacterSet tag in the written image file (which indicates the encoding) to UTF-8.
On macOS you can also add and change metadata like title, GPS and creation data in movie files (like .mov and .mp4).

Create thumbnails of your image and movie files

With Troi File Plug-in you can create thumbnails of your image files in any size, including square thumbnails, which is great for presenting multiple images to a user in a compact grid. We have added a grid view to the Thumbnail example file, which demonstrates (in a simplified way) how to do this. We also added the possibility to add a name when creating a thumbnail with the TrFile_CreateThumbnail function. The name is normally not visible, but will be used for example when you perform an Export Field Contents action later. Another feature is the possibility to make thumbnails in the PNG format, with an alpha channel. This means that the thumbnail will have the same transparent areas as the original image.
On macOS you can also create a thumbnail of your movie files (like .mov, .mp4 etc.). The plug-in will create a thumbnail of the first frame of the movie.

Check the type and availability of items

Before manipulating files and folders with the many functions Troi File Plug-in offers you, you can check their type and availability, thus avoiding possible errors. The function TrFile_GetTypeOfItem provides an easy way to see if a path points to a folder, file or package folder (macOS). It can also indicate if a file is an alias file (or shortcut on Windows). Use the TrFile_Exists function to see if a file or folder you want to manipulate exists and the TrFile_IsFree function to see whether a file is not in exclusive use by a different application or locked.

Exchange two files on disk

The plug-in’s ExchangeFiles function lets you quickly exchange two files that are stored on your disk. Very handy when updating existing files: work in a draft version first and when your draft is ready, replace the original file with just one script step. Also works when the files are located on different disks!

Create and resolve alias files

The plug-in’s CreateAlias function lets you create an alias file (or shortcut) from a source file or source folder. Resolving an alias file is easy with the ResolveAlias function. It returns the path to the destination of the alias file. If the alias is broken you can use the switch “-ReturnLastKnownPath” to get the last path the alias pointed to.

Zip and unzip files and folders

The plug-in’s CreateZip function lets you create a compressed archive of files and folders. Expanding ZIP files is easy with the UnZip function. You can specify the folder where the unzipped items need to be placed. The GetZipInfo function lists the items (files and folders) inside a ZIP file. This allows you to check what’s inside a ZIP file before you unzip it, so no unwanted overwriting of existing items occurs.

Powerful listing of folders and searching

Troi File Plug-in lets you recursively list the contents of a folder with one call to the plug-in. The plug-in will return a list of all files and/or folders and all the subfolders contained in the folder you are listing. This makes processing all the items in a deeply nested folder very easy, like for example listing all the Word documents contained in a folder.
On macOS you can optionally even list the internal contents of a package folder (like for example a macOS app).

Insert text into a file

Troi File Plug-in can substitute text in and append text to an external (text) file. You can search for a text string in a file and substitute it with a different text. You can substitute text and have the result saved in the same file! And you can use replace strings of up to 150,000,000 characters, making it possible to substitute tags with much longer replacements in template files. With the function TrFile_InsertContents, you can insert text into a file at a specified position.

Get file icons

The GetIcon function gets the icon of a file. It can create icons in sizes varying from 16×16 to 1024×1024 pixels and with double resolution, which is great for retina screens.

Drag your files and mails into FileMaker

Troi File Plug-in allows you to drag one or more files or folders on a FileMaker window or even a drop zone. The paths of the dropped items can then be handled by a triggered script, for example to put them in a container field. You can specify up to three drag destination rectangles (even on the same window), and each drag can trigger a different script.
The drag and drop functionality includes Mail Drop (macOS only). You can drag one or more emails from the to the FileMaker window. Add the switch “-AllowMailDrops” to the switches parameter of TrFile_DragAndDrop function to enable this extra functionality. The DragAndDrop example file reflects the Mail Drop functionality with an extensive example demonstrating the handling of single and multiple Mail Drops.

Command your shell

With the TrFile_ExecuteShell function you can execute a command in the command shell of the operating system. On macOS this will be a command executed in the UNIX Bash shell, and on Windows this is the Windows CMD shell.

Suggested Uses

Troi File Plug-in can be used in a lot of ways. Its 80 functions and 38 script steps give you a universal tool that can be used in a lot of databases. Below are a few suggestions on how Troi File Plug-in can be useful:

  • list the contents of a folder and process newly added files
  • check the integrity of files on disk with a hash or get code sign info from applications
  • update solutions, by moving (database) files into place
  • read and write custom formatted files, for example from legacy systems
  • catalogue complete projects, including pictures
  • manage images, movies and other files
  • launch files with their appropriate application directly from FileMaker

The possibilities are only limited by your imagination!

Version 10.0 (for FileMaker 13 to 17) (May 15, 2018)
New functionality

  • Tested and made compatible with FileMaker Pro 17.
  • Rewrote and modernized the low level file handling code of the plug-in.
  • Added new Exchange Files script step, which can (quickly) exchange two files on disk. With the checkbox “Allow different volumes” you can even exchange files on different disks. Note that this may take more time.
  • Added new TrFile_ExchangeFiles function, which can (quickly) exchange two files on disk. When you add the switch “-AllowDifferentVolumes” the plug-in also can exchange files on different disks. Note that this may take more time.
  • Added new TrFile_GetCodeSignInfo function, which returns code sign info of signed files (like applications and plug-ins).
  • Added new TrFile_GetFileStructure function, which returns the structure of a movie file. It can analyze a movie file (.mov) and return a list of all movie boxes (formerly known as atoms) in the movie. The movie boxes are indented to visualize the tree structure of the boxes. The result can be formatted as XML or as a more readable list of movie boxes. It can also return the structure of a ISOBMFF (ISO base media file format), for example MP4 or HEIC.
  • Added new switch “-AllowDifferentVolumes” to the TrFile_MoveFile function, which allows the move of the file between different volumes (disks). Note that moving a big file across disks may take more time.
  • The plug-in now indicates if an external script step is compatible with a product. The step is shown in grey if it is incompatible for that product (for example for iOS) in the script editing pane (center) and the script steps pane (right).
  • Added new switch “-AddFolderSuffix” to the TrFile_ListFolder function: this will add a trailing slash to folders in the result, making them recognizable as folders.
  • Added a new switch to the TrFile_DragAndDrop function: “-ScrollDropZone” to help with the scrolling behavior when you use a drop zone for the drag destination. When you add the switch the position of the dropzone will scroll too when scrolling the FileMaker window.
    This is also implemented in the script step “Add DragAndDrop Handler” with the checkbox “Scroll the drop zone”.

Improved metadata support

  • Improved the TrFile_SetMetaData function with the switch “-SetEXIF”. The plug-in is now compliant with EXIF v2.3.1. It writes tags introduced in EXIF version 2.3.1, like LensMake, LensModel and LensSerialNumber and timezone tags. The plug-in also handles these tags: ambient temperature, humidity, pressure, waterdepth, acceleration, sensitivity type, standard output sensitivity, recommended exposure index. Finally the plug-in handles the GPS tag GPSHPositioningError, which indicates horizontal positioning errors in meters.
  • Improved the TrFile_SetMetaData function with the switch “-SetEXIF”. The code has been rewritten and the plug-in now writes EXIF data that is better readable by PHP.
  • Added more tags to be written when using the TrFile_SetMetaData function and the switch “-SetEXIF”: the plug-in now correctly writes the tags: WhitePoint and PrimaryChromaticities. It now also writes tags which are not part of the EXIF specification, but may exist in the EXIF data in some images. This can be tags like ProcessingSoftware or DocumentName.
  • (macOS) Added initial support for HEIC (High Efficiency Image File Format) image files: the TrFile_GetMetaData function with the switch “-GetImageDescription” now returns a description.

Other improvements and changes

  • Improved handling of files located on remote volumes like WebDAV.
  • Fixed a problem with the TrFile_Exists function, where certain incorrect paths with double colons would result into a 1 as result.
  • Improved the TrFile_DragAndDrop function so that it works with FileMaker Pro 17.
  • (macOS 10.13.4) Fixed a problem with the TrFile_DragAndDrop function when using the switch “-AllowMailDrops”, where an incorrect path to the temporary email file would be returned. The plug-in now returns the correct path. In some cases the Mail app does not create the temporary email file, the plug-in then returns the complete drag information, which can be parsed to get the correct location of the email.
  • Added example script to the SelectFile.fmp12 example file which demonstrates how to use the switch “-HideInvisibles”.
  • (macOS) The minimum supported Mac OS X version is now 10.8.

Version 9.1 (for FileMaker 12 to 16) (February 20, 2018)
New functionality

  • Added new TrFile_ResolveAlias function, which will resolve an alias file (on macOS) or shortcut (on Windows). It returns the path to the destination of the alias file. If the alias is broken you can use the switch “-ReturnLastKnownPath” to get the last path the alias pointed to.
  • Added extra switch “-AddAliasInfo” to the TrFile_GetTypeOfItem function. If an item is an alias file (or shortcut on Windows) the result will be “file (alias)”.
  • You can now add the “-DontResolveAlias” switch to the TrFile_SelectFileDialog function. When you select an alias/shortcut the result is the path to the alias itself (and not the destination path where the alias points to).
  • (Windows) Added code signing to the plug-in for Windows (On macOS code signing was already added in version 8.0).

New functionality for movie metadata

  • Added new functionality to the TrFile_GetMetaData function: when using the switch “-GetMovieMetadata” the plug-in now returns all metadata embedded in QuickTime movies (with extension .mov) and all variants of MP4 movies. This returns a list of metadata in the movie, returning for example Artist, Creation date and Description.
  • Added new functionality to the TrFile_GetMetaData function: when using the switch “-GetMovieGPS” the plug-in now returns the GPS location data of the movie. With an extra -Format switch you can specify how the location is returned:
    Format switchDescriptionExample
    -Format=DecimalDecimal coordinates (default)+52.0907 +5.1213 +112.000
    -Format=DegMinSecsLatitude, longitude (in degrees,
    minutes and seconds) and height (in meters)
    52° 05′ 26.5″ N, 5° 07′ 16.7″ E, 112m
    -Format=ISO6709Formatted according to ISO 670952.0907+5.1213+112.000/
  • Added new switch “-GetMovieCreationDate” to the TrFile_GetMetaData function: when using this switch the plug-in returns the creation date (including time + timezone) of the movie (if present as metadata). This might return for example: “2018-01-31T16:29:07+0200”
  • Added new functionality to the TrFile_GetMetaData function: when using the switch “-GetXMP” the plug-in now can read embedded XMP metadata in movies. The plug-in supports reading XMP metadata for QuickTime movies (with extension .mov) and all variants of MP4 movies.
  • Improved the example file ManageMedia.fmp12, it now demonstrates how to retrieve metadata from movies (including XMP).

Other improvements

  • Improved the TrFile_GetMetadata function. Added new switch “-SourceUTF8CharSet”, to be used with the switch “-GetIPTC”. The IPTC metadata of the source image file will forced to be read as UTF-8 encoded.
  • Updated the FileManipulation.fmp12 example file to show the TrFile_ResolveAlias function.
  • (Mac OS) Fixed a possible bug in the TrFile_Substitute function, when substituting in place: there are no longer spurious extra characters at the end of the new file when the replace string is shorter than the search string.
  • In the TrFile_Substitute function, when the search string is at the end of the source file the destination now has the correct end character.
  • (Mac OS) Fixed a bug in the TrFile_Substitute function on macOS 10.13 (High Sierra): when you substitute in place this no longer gives an $$-50 error code as result.
  • (Mac OS) Improved the reliability of the TrFile_SetMetadata and TrFile_InsertContents functions on macOS 10.13 (High Sierra).
  • (Mac OS) Fixed a possible memory leak in the TrFile_GetFolderSize function.
  • (Mac OS) Fixed a compilation problem with code signing and extended attributes in macOS 10.12 (Sierra).

Below are a few things our users had to say about Troi File Plug-in:

“We have used the Troi Plug-In for years and it has worked flawlessly with our Filemaker Pro 11. I have had to reach out several times to purchase a new product or when I required a download for a new computer. I always receive a response within the hour and Troi is amazing in support. Thank you.”

“I bought Troi File Plug-in a week ago. Thus far, the plugin has worked absolutely flawlessly! I was using a free plug-in for (if exist) file checks and it occasionally returned incorrect results. Troi has been 100% since the first script run. Seriously, seriously good, clean software! Worth EVERY penny! I have yet to see any malloc/free issues and I’ve not needed a single reboot (whereas the free plug-in required more hands-on admin). The Troi plugin is simply miles and away superior.”
John Czlonka – CTO & Lead Software Architect, Marcon Pipelines, Inc., Calgary, Canada

“I have been using the file plugin for a long time (10 + years) and it has been great. Very easy to use and powerful. Awesome work :)”
Steven Durow, Director of Data Analysis Department, Fargo Public Schools, Fargo ND, USA

“Your customer service is first-class, there are many companies that could learn a lot from you about how to help and advise their clients. I really appreciate it.”

“I like to thank you for an excellent plugin that has made many of my solutions two steps better than I ever could do in pure FileMaker.”
Johan Hedman, certified FileMaker developer at PositionEtt AB, Sweden

“I really have to say, that Troi File Plug-in is a fantastic extension for Filemaker. Troi opens a wide range of possibilities to improve our database and helps us a lot, to make the photo-handling easier.”
Daniel Stöckli, Switzerland

“We have used a single version of the original Troi File classic plug-in for a several years, converting last week to a 10 user of the v4 version for Filemaker 8+.
I was amazed how quick and easy it was to convert our code, as we use the Troi File functionality in about 40 instances across about 15 scripts.
Troi File has been critical to our ability to extend Filemaker’s functionality to allow us to generate a dynamic website with hundreds of pages made up of complex HTML, XML, Javascript and PHP. It would have been impossible to achieve this result without Troi File, which has proved to be a reliable, consistent, and high performance Plug-in.

Thank you for developing and supporting Troi File so professionally, in the future I’m sure we will use more of your products.”

“I think this is a fantastic product, it does what it says and I am overwhelmed by the functionality that is offered.”
Peter Cross, read his complete review of Troi File Plug-in on the FMPug website

“I just want to let you know how highly I think of your product, Troi File. I’ve been developing a commercial solution that makes extensive use of the plug-in. It’s easy to use and most importantly, it’s rock solid. I’ve emailed you support questions from time to time and they are always answered with the information to solve the problem.
I cannot praise your product enough.”

Randy Lawrence, Absolute Advantage, Inc.

“Two weeks ago I had a very intensive project; full automation of a data conversion routine involving import and export of thousands of files. The Troi File Plug-In (and your very helpful and timely advice) made it all happen and get delivered on time.
In the past years of doing FileMaker development the most visionary and extensive projects I have been involved in have used Troi Plug-Ins as an essential component. Troi Plug-Ins give the ability to automagically harness system level processes; the simplest way of describing it is a “Wow” factor on the client’s side and a fundamentally elegant, straightforward, and fast scripting process from the developer’s perspective. They put a powerhouse of programming behind FileMaker’s ease of use.
Although I have used them for a wide range of functions I still feel I’ve only scratched the surface of Troi Plug-Ins possible applications. Much thanks for providing an essential tool to FileMaker developers.”

“Thought you might be interested to hear about something we’ve done using Troi File and Troi Coding.” Read how Noam Sturmwind of Oak Bay Softrends, Inc. manages to update the local files on his client’s workstations by automatically downloading a new copy of the files when the workstation connects to the server. “Not only does this save us a lot of time in re-installing on each workstation, it also means that we don’t have to worry about local files becoming corrupted.”

“Troi File Plug-in is a truly great product. I just wish I had looked into it properly when it first came out. If I had known just how powerful this tool was I’d have bought it for all my clients years ago.
Many thanks for a great product”

Peter Makin, Makin Rochard Ltd., United Kingdom

“Don’t leave home without Troi File Plug-in.”
Doug Rowe, Robyte Consulting

“Thank you for your new plug-in!
I bought it in about 10 seconds after I saw it can do exactly what I have been trying to do with Applescript unsuccessfully.
Using Filemaker to organize my cruise reviews, I was looking for a convenient way to export the html to a file.
I had been using the legacy Keyquencer to copy and paste information into a text-editor, and then save the file. To update my html files, this would take about 2 hours!
Your timing could not have been better. Now I can do the same task in about 2 seconds. Well worth the price of the plug-in!
Thanks for all your great work”.

Greg “Pepe” Giese,

“This plugin has become somewhat integral to many of the solutions I’ve worked on here. It’s a lifesaver!”
Tony Pottrell, Human Engineering

“At the recent suggestion of Dana Perry, I took a look at the Troi File Plug-in in the context of testing for the existence of the Adobe Acrobat Reader program (before launching PDF files from FileMaker). My study of the plug-in confirmed for me the great power of this tool for a variety of other tasks, including the automation of upgrades. I developed a routine with FileMaker and the Troi File Plug-in that I thought might interest other users.” Read more about it here.
Vince Lackner, The Lackner Group, Inc.

“As you might be aware, Brushfire for the Mac originally was written using AppleScript as the glue to pull the components together. When we ported Brushfire to the PC, we decided to use the Troi File plug-in. With Brushfire 1.5 we are using the Troi File plug-in on both Mac and PC versions. Not only was development with the plug-in smoother and easier than the AppleScript development, but the resulting code is more solid and robust. Since the switch to the Troi File plug-in our customer support telephone calls have dropped over 20%. I only wish we had started the project this way! Thank you for providing such an excellent tool.”
Russell Kohn, Chaparral Software & Consulting Services, Inc.

“I can’t thank you enough for this plug in. It is incredible what I have been able to do with FileMaker now that I have found your plug in. It’s simple to understand and I don’t think I could use FileMaker without it. I use it to create thousands of web pages from my FileMaker database very easily.”
Ben Levitan, USA

“Hello, Troi folks!
First, thanks for a great plugin in TroiFile! I’ve been using it to help power a great web site, (not available from 4:00 to 4:30 AM CST (GMT-7)). There we are using TroiFile, in concert with some calc fields in FMP, to detect whether a given house listing in our “available properties” FMP database actually has a picture on the hard drive or not, by using the TroiFile GetSize command – if it has a size, it’s got a picture! Saved our bacon for sure, as the database we’re importing the housing data from doesn’t have any kind of field that would otherwise let me know if any given record has an associated picture or not. Many thanks!
We’re also using TroiFile to write lasso-enabled template-based web sites for us. It writes from an FMP database which stores the raw HTML, and then substitues in customer-specific data right before TroiFile writes that html to a file out on the web server. We’ve got it writing about 500, 3-page websites every week for us, at a rate of about 1 complete site in 0.13 seconds on a rather modest AMD K6-2 450. Talk about profitability (and more time for our web designers to do other things)!”

John Krische, Krische Database Systems, Topeka, KS, USA

“From the US side of the pond, I offer my sincere thanks for the work you put into the File Plug-In. I didn’t realize the limitations that are inherent to FMP5 (Win) until I built my solution and found I couldn’t include badly needed features. After being directed to your web site by a fellow developer I downloaded and tested the evaluation copy. Shortly thereafter I purchased the Developer License.
What a Blessing the plug-in has been. It is everything that is advertised and then some. Thanks for an excellent piece of software. If my FMP solution is half as helpful and successful as your File Plug-in, I will be elated.”

Gary Hopps, Carthage, NY, USA

“I am having much success with your “Troi File” Plug-In- Thank You for making such a GREAT Product! Keep up the good work- Your products are an asset to the Filemaker community!”

Enrique Pardo, edesign graphic studio, Geneva, Switzerland

“I tried Troi’s file plug in and the demo file sucked in a folder full of JPEGs from my Mavica 91. All the plug in needs is a little sound file that makes the sound heard when emptying the contents of a container via a straw….slurrrrrpppp…”
Jack Rodgers, FileMaker developer

“I grabbed this plug-in, took it for a spin and it is totally the tool that I’ve needed for many a moon. AND it has many many other features that have my wheels turning – Thank you for this piece of Magick!”
