Bulk Rename Utility

I have followed all of the suggestions, like: closing BRU and opening up the UNC path in Windows Explorer first, then opening BRU and pasting the UNC path in the path box - nothing...
I use Jump to path with the UNC path and nothing...

Does BRU support UNC paths without needing to map the network drive first? (Mapping the drive is a security risk since malware hits mapped drives first, but cannot access UNC paths)

It does (work with UNC paths).
Mapping is not required.

Are you running BRU "as Administrator".
If so, it could be a credentials issue (where you, as a normal User, are logged in "to the path", where "Admin" is not).

(Oh, BTW, you've posted in the BRC section, not that it matters.)
