Problem with a couple of the proposed suggestions is that if any of the files/directories have special characters, they will not be deleted. Doing an -exec in the submitters lins is really time consumming and better efficiency is done by piping the names to xargs and invoking the rm/rmdir in as few times as possible.
find /media/Server/VPS/dailySQL -type f -mtime +140 -print0 | xargs -0 rm -f >/dev/null 2>&1
find /media/Server/VPS/dailySQL -depth -type d -print0 | xargs -0 rmdir >/dev/null 2>&1
The second line deletes all the old files. I put a file in the top level directory to save it from destruction on the first line and finally you run through the directories depth-first and simply try to rmdir. If there is something still present, the rmdir will fail. Depth-first is necessary to remove empty sub-directories before a given directory is attempted to be removed.
Finally, notice -print0 and the -0 parameter on xargs. This allows you to process files that have spaces or other meta characters in them properly. This feature is available on most Linux systems I have been exposed to lately.
This is the type of scripting I used to remove /tmp and /var/tmp items.
