Okay, so in the past year that I have had my treo, through the various installations and deletions, I think I have built up a large number of orphaned files. Is there some way to go through and figure out what files I can safely delete, and which ones I need (for current programs, just to run smoothly, etc). I know each file has a four digit code to tell who the creator is, but I have no idea how to read them, or what they mean.
