This program removes duplicate messages from your GCP message files.  If you tend to keep a lot of messages around, it can shorten your .MSG files thus saving you disk space and increasing GCP performance.

The program is non-destructive.  It builds a new .MSG file, renaming the original as <forumname>.OLD.  It is up to you to delete the .OLD files once you're sure you no longer need them.

The main window is yer basic file chooser.  Use the drive buttons and double-click on the folders to get to where you keep your .MSG files.  This is saved in an INI file, so you only have to do it once.

Double-clicking a message file (book icon) launches a secondary window that starts trimming the file.  The program is multi-threaded so you can launch several trimmers at once.  Each trimmer has a progress indicator and a cancel button, so you can stop them at any time.

When a trimmer finishes, its "cancel" button will change to a "close" button.  It also reports the size, in bytes, of the original file and the new .MSG file.  
