Message: Cannot close file
Cause
If
the file is on a floppy disk, the disk may have been removed from the
drive.
If the file is on a hard
disk, the disk structure may be corrupt.
What Can I Do?
If
the file is on a floppy disk, check the disk is correctly inserted in
the drive.
If the file is on a hard
disk, run your disk diagnostic utilities to check for a corrupted disk
structure.
