Originated in

Troi File Plug-in 1.0


FileMaker Pro 16 to 19


You can use FileMaker styled paths, like “filewin:/C:/MyFiles/test.txt”.
See also the function TrFile_SaveFileDialog to get a filepath for the file.
Starting with Troi File Plug-in 12.0 you can omit filemac: or filewin: too! Any path starting with a slash will be parsed as a FileMaker style path (of the platform FileMaker is running).


Set Field [ gErrorCode ; TrFile_CreateFile ( "-Unused" ; "C:\Testtext.txt" ) ]

This will create the empty file “Testtext.txt” on the C disk.

Set Variable [ $ErrorCode ; TrFile_CreateFile ( "-CreateFolders" ; "/macHD/users/ad/nw/foldB/myfile.log" ) ]

This will create the empty file “myfile.log”. This will also create new folders if they don’t exist in the specified path, for example the folders “nw” and “foldB” may be created.

Example 2

We assume that in your FileMaker file the following fields are defined:

  gErrorCode		Global, number
  gDestFilePath		Global, text 

gDestFilePath should contain the path to the destination and should not exist, for example “D:\Logs\L2000_01.TXT” (Windows) or “Mac HD:Logs:Log 2000_01” (Mac). In a script add the following scriptstep:

Set Field [ gErrorCode ; TrFile_CreateFile ( "-Unused" ; gDestFilePath ) ]

This will create the file indicated in the gDestFilePath.
