File Exclusions vhdx

Can someone explain what im doing wrong. Im looking to backup both these dir but to exclude those file types

Think that you’re missing the trailing backslash before the trailing wildcard in your screenshot - so it is looking for a folder that has anything after the “Hard Disks” or “VirtualBox” in the path…

Thought so to. I’m actually looking for it to exclude this types within the directories I listed. So this should’ve worked. In any case I lost patience and did a reinstall, now it’s working ok
