Troi File Plug-in 5.0


FileMaker Pro 13 to 17


This function provides an easy way to see if a path points to a folder or a file. Please note that in the future other types may be returned.

About package folders: these are folders that behave more like a file. For example all Mac OS applications are package folders.


TrFile_GetTypeOfItem ( "-Unused" ;  "C:\Test.txt" )

This will return “file” if the file exists (and is a file). If it does not exists $$-43 is returned.

Example 2

Set Variable [ $whatKind ; TrFile_GetTypeOfItem ( "-Unused" ;  "filemac:/Mac HD/Users/Smith/Data Folder ) ]

This will set the variable $whatKind to “folder” if the folder exists (and is a folder). If it does not exists $$-43 is returned.
