Prevent MS Office temp files from backing up

Hi,

I couldn't find the proper answer in the Help file, so please help me with that.

I've set up a profile with versioning of my work documents folder. It's scheduled to run on every file change. However, I don't think temporary files created by Word, Excel etc. are necessary to be backed up.

Thus I want to set up an exclusion filter but have some doubts about using wildcard expression. Will the following combination:

*\~*.*

be all right? I'm particularly concerned about "~*" part as specifying the file name starting with tilde.

Or would it be safer to set up particular filters like e.g. for Word?

*\~*.doc*

Others for Excel and Powerpoint would go the same way.
