Does anyone know what are prf files, some of the example filenames are prf8d.tmp or prf9c.tmp. They always start with prf with a number and a letter before the extension. We have roaming profiles and our server is very slow at when users shutdown their machine. I saw a few prf files that were about 500 mb in one of the user's profile. Does anyone know where they come from, is it an application producing these files?
