Eudora Error Message: "Could not open file for writing Cause: No such file or directory exists"

When a user receives a new e-mail in Eudora, an error message shows up (maybe multiple times) that states Could not open file for writing Cause: No such file or directory exists. The problem comes from attachments and/or embedded objects in the e-mail that are named the same. After 999 of the same filename for the attachment/embedded object, the error message shows up. The solution is to clear out old files in the attachment/embedded folder. Eudora forum regarding this case can be found here: http://eudorabb.qualcomm.com/showthread.php?t=1967
