Problem

&FSUF is not working with CFT 3.3.2 on Linux

Sending file_test.TXT

&FROOT on the receiver contains the full filename sent, &FSUF is empty ?

Doing the same with a CFT for Windows, it works.

Resolution

To enable the option to separate the file name and extension in Unix, set the following UCONF value to yes:

cft.unix.parse_file_name_suffix=yes

Then it will work as it works for your Windows CFT.
