In case you ever use a non-standard extension (length different from 3), you may consider using the filename functions instead:

MemoFileName=forceext(filename, "FPT")

Also, for other filename manipulation, check DefaultExt(), JustFName(), JustStem(), JustExt(), ForcePath() functions. They look much neater than using at(), Substr() etc, and you don't need to worry whether the path name contains the final backslash or not.

BTW, FTP is File Transfer Protocol. FPT is the memo file extension. Take care.
