Unable to create the file filename.
The named file could not be created on the current drive, and therefore cannot be restored. Either you do not have Write privileges on the parent folder, or there is not room on the target disk.
Check to see that you have permission to write to the parent folder. If you do not, ask that permission be given to you, or log in as a user with the necessary permission. Check the available space on the disk. If the disk is full, delete some unneeded files to make room for the restored file.
