Problem

Tranfer CFT truncates the filename (path and actual name of the file) displayed in the log whenever the length exceeds a limit.
Tranfer CFT reserves a string length of 44 characters for the filename for the display.

Example:

filename :
C:\Windows\System32\en-US\Licenses\Volume\Professional\license.rtf

content of cftlog for the message id CFTT88I:
CFTT88I+<IDTU=A0000238 WORKINGDIR= FNAME=C:\Windows\System32\...fessional\license.rtf NBC=539 DURATION=0s>

Resolution

To get the full filename in the CFT log you can issue the command CFTUTIL WLOG MSG=&fname from an End Of Transfer exec script.
