Whether I used a mapped drive letter, or a UNC path, if I try to restore a backup from a network drive it fails, with a message like "Cannot open file".

I fully understand why Firebird won't open a database file on a network drive, but I'm trying to do the restore to a DB on a local drive. And I can't understand what problem is trying to be avoided by whatever coding was done to prevent backups being restored from network drives.

Can someone please explain? Any chance this might change? I'm using Firebird 2.5.
