Compatibility

Considerations
See also the functions TrFile_GetFileSize and TrFile_GetResForkSize.
You can use FileMaker styled paths, like “filewin:/C:/MyFiles/test.txt”.
Example
Assume there is a file “Read me” with the text “Hello!” in it. Then:
Set Field [ MyTextField ; TrFile_GetDataSize ( "-Unused" ; "Disk:Read me" ) ]returns 6, which is the size of the data in the file. The total file size may be bigger.
Example 2
We assume that in your FileMaker file the following fields are defined:
gFileSpec Global, text
gSize Global, numbergFileSpec should contain the path to an existing file, for example “D:\Readme.txt” (Windows) or “Mac HD:Readme.txt” (macOS). In a script add the following script step:
Set Field [ gSize ; TrFile_GetDataSize ( "-Unused" ; gFileSpec ) ]This will fill gSize with the size of the data.
