Hi, I'm having a hard time with the filter rules syntax, and thought someone may already have done this and would share his rules. In the user profiles, I do want to backup the outlook files in the ridiculous path "c:\documents and settings\username\local settings\application data\microsoft\outlook\". But not anything else under these ...\user\local settings\ directories. I have 2 backup scripts. One to backup the whole C:\ drive, and another for just the user profile. For the whole disk backup there is also a lot of stuff which either cannot be backed up (files open and locked by Windows), or is useless (pagefile, Prefetch, etc.). I can slowly find out and exclude these, but maybe someone already has gone to the trouble of listing these in his filters file? The root folders are obvious (System volume information, recycler, etc.), but there are many more buried in Windows\ and maybe elsewhere. Thanks for any help, particularly for the "exclude dir except one sub-sub-dir" problem, Mi
