ArcCatalog shows that I have a ~$NAMEOFFILE.xlsx in D:\
I receive the error "Failed to connect to database. General function failure External table is not in the expected format." when I try to delete it. The problem is there is no NAMEOFFILE.xlsx that shows in Windows Explorer or the command prompt (hidden files are shown). I am able to copy the file for some reason, but I'm just trying to figure out how to get rid of the file once and for all.
This problem has persisted from 10.0 to 10.1
