Text-files don't have any special header, so this should not be the problem.
There may be a difference in the end-of-line marker. The official separator is chr(13) + chr(10). However, some programs might use only chr(13), or only chr(10).
To check this theory - or see what other differences there might be, you would need a hex editor.
I think you can find one somewhere amongst the utilities that come in the VFP directory. Or perhaps it needs to be installed separately.
Otherwise, check
www.download.com - you should probably find a free hex editor there.
