The FileType is a 4 character code used to designate the type of file. For example: FileMaker 7 files have a FileType of “FMP7” and Applications have FileType of “APPL”.

Originated in

Troi File Plug-in 1.0


FileMaker Pro 16 to 19


FileType in macOS are not used much anymore, but are still supported. This function is not available in Windows.

If the file type is empty the function returns: “0000” (4 zero’s) .

You can use FileMaker styled paths, like “filewin:/C:/MyFiles/test.txt”.


Set Field [ result ; TrFile_GetFileType ( "-Unused" ; "KES:test.fp7" ) ]

This will (probably) return “FMP7” which is the FileType for FileMaker Pro 7.

Example 2

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

  fileType		text
  gFilePath		Global, text

gFilePath should contain the path to the file, for example “Mac HD:Logs:Log 1” (Mac). In a script add the following script step:

Set Field [ fileType ; TrFile_GetFileType ( "-Unused" ; gFilePath ) ]

This will store the FileType of the file specified by gFilePath in the field “fileType”.
