Comment 3 for bug 1571440

I saw this also on Windows 7. The first time the delete operation reports a success like

Delete 24B C:\Users\foo\AppData\Local\Microsoft\Windows\Explorer\thumbcache_1024.db

The second time it sees the file but reports an error like

[Errno 2] No such file or directory: u'\\\\?\\C:\\Users\\foo\\AppData\\Local\\Microsoft\\Windows\\Explorer\\thumbcache_1024.db': Command to delete C:\Users\foo\AppData\Local\Microsoft\Window\Explorer\thumbcache_1024.db

Now the Windows DIR command shows thumbcache_1024.db, but the DEL command reports "Access is denied."

So these are not normal files
