Possible causes:

• The file you tried to read or link is corrupted. Restore a backup copy of the file to your disk, and then try the operation again.
  
  
• The file format is not recognized. If the file is a Btrieve, dBASE, or Paradox file, run Setup to install the installable ISAM, and then link the file.
