RoamingCustom.dic

Guys.

Bit of a head scratcher. I need to backup and then at a later date restore a users RoamingCustom.dic in the location below. The issue is that in the path there is a small identifier which is different on each users machine. eg the a27060d1 in the path. I need to come up with a way that will back up the RoamingCustom.dic and restore it regardless what that directory is called.

Any ideas?

C:\Users\USERNAME\AppData\Roaming\Microsoft\Office\15.0\a27060d1\Proofing\RoamingCustom.dic

Thanks in advance
