The issue is with how the /D option is used—it needs to be applied to the forfiles command directly, not inside the cmd /c part.

Try modifying your code like this:

echo off
forfiles /p "c:\users\J33333\Desktop\DDrive\test" /s /m "TS*.xmt" /D -30 /c "cmd /c del @file"
exit

Here's the breakdown:

• /m "TS*.xmt" is used to match files starting with "TS" and ending with ".xmt".
• The /D -30 option filters out files older than 30 days.
• The @file in the cmd /c del @file part refers to the current file being processed by forfiles.

This should delete only the files that match both criteria: filenames starting with "TS" and older than 30 days.
