switches modifies the behavior of the function

Originated in

Troi File Plug-in 1.1


FileMaker Pro 17 to FileMaker Pro 21 (2024)


TIP: You can also use this function to rename a file
See also the functions TrFile_SelectFileDialog and TrFile_SaveFileDialog to get a filePath for a file.

When the function returns the error code $$-1303, you can use the switch -AllowDifferentVolumes.


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

  gErrorCode		Global, number
  gSourceFilePath	Global, text
  gDestFilePath		Global, text

gSourceFilePath should contain the path to an existing file, for example “D:\Logs\Log01.TXT” (Windows) or “Mac HD:Logs:Log 1” (Mac). gDestFilePath should contain the path to the destination and should not exist for example “D:\New\L2000_01.TXT” (Windows) or “Mac HD:New:Log 2000_01” (Mac). In a script add the following scriptstep:

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

This will move the source file to the path indicated in the gDestFilePath.

Example 2

Renaming a file: assume your C disk already contains a file “Testtext.txt”. We assume that a global number field gErrorCode is defined. Create the following script:

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

This script will move (rename) the file “Testtext.txt” to the “NewName.txt” file in the same directory. Note that on Mac OS the paths will be like: “Work Disk:NewName.txt”.
