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


Set Field [ result ; TrFile_Reveal ( "-Unused" ;  "C:\readme.doc" ) ]

This will make the file visible in a Windows Explorer window and select it.

Example 2

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

  gErrorCode		Global, number
  gFilePath		Global, text

gFilePath should contain the path to the file, for example “D:\Logs\L01.TXT” (Windows) or “Mac HD:Logs:Log 1” (Mac). In a script add the following script step:

Set Field [ gErrorCode ; TrFile_Reveal ( "-Unused" ;  gFilePath ) ]

This will show the file specified by gFilePath in the Finder or Explorer. It will open the enclosing folder and show the files selected.
