batch file - forfiles with UNC path

Question

I am trying to use forfiles to delete files that are older than 7 days. The files are in a UNC path. Below is the script that I am using.

Forfiles -p \devexpressC$FULL -s -m *.* -d -7 -c "cmd /c del /q @path" 

But I get an error mentioning that UNC paths (machineshare) are not supported.

There appears to be workarounds available but cannot get a clear answer googling.

Answer 1

Enhanced solution to the PA's first answer is:

PushD "\devexpressC$FULL" &&(
    forfiles -s -m *.* -d -7 -c "cmd /c del /q @path" 
     ) & PopD

The PushD command maps the UNC path to free drive letter automatically, so this is portable approach. Found in http://www.petri.co.il/forums/showthread.php?t=24241.
