"Macintosh: Error -39 ""End Of File"" Meaning

I am getting a -39 error when I try to open a document. What does the error mean and what might be the problem?
The -39 error is an "End Of File" error. The most likely cause of the error is a corrupt data file. The only real fix is to restore the data file from a backup or recreate it if there isn't a good backup available.
