Found this little progrm to be very useful.
ImageClean Utility is a fast and simple utility that cleans up the ET game folders by deleting junk pk3 files, mini-mods, annoying custom menus, and excessive server files. It will also reduce the number of total files in your etmain folder since too many files causes game instability and corruption. It also has the option to delete the profile.pid file.
The utility is safe, and does not delete stock ET game files, large maps, or major mod files. It does not install anything on your computer. You can run it as often as you like.
FEATURES:
* Aggressive deep scanning action
* Removes unwanted clan menus
* Restores default ET menus
* Prepares players for new clan menu installs
* Removes trash etmain files
* Reduces disconnection drops
* Eliminates the hassle of purging or reinstalling
* May fix mod problems caused by .pk3 errors
* Removes partially downloaded temp files
* Removes profile.pid so cvars don't reset
