SUMMARY
The ATT attachment file is stored within one of the 16 subdirectories
of the ATT subdirectory. If the subdirectory is not there, or the user
is unable to create a file there, the following message will appear:
Error in sending attachment(s).
To prevent this error from occurring, use the MS-DOS MKDIR command to
create the missing subdirectory.
