Looks like due to some kind of encoding mixup, the file name that is
eventually passed to unlink does not match the name in the 'Archive'
directory.
I'd be tempted to create an ../Archive.bak directory, move everything
apart from the file you can't delete to .bak directory, and do an 'rm
-rf ../Archive' .. and if that works an 'mv ../Archive.bak ../Archive'.
Another option that comes to mind is to use emacs' directory editing
capabilities.
On the other hand I'm not too sure about the file's inode changing from
one stat command to the next. Maybe talk to the vendor's tech support?
