Error Message:

Unexpected end of file

Explanation:

The Comp command unexpectedly reached the end of one of the files being compared. If you see this message with the Comp command, most likely the file allocation table (FAT) entry for the file has been corrupted, causing part of the file to be lost.

User Action:

The Chkdsk command with the /f switch may be able to recover all or part of the missing portions of a text file.
