When I use big-find to FIF on \\joes-pc\c\program files, the search fails.
The search results window shows this:
Find all "things", Match case, Regular expression (Perl), Subfolders, "\joes-pc\C\Program Files", "*", Exclude: ".git\;*.Z;*.a;*.avi;"
Failed to open: C:\joes-pc\C\Program Files
Total found: 0 Matching files: 0 Total files searched: 1
