If you have documents dating back to 1998 you DO have DocuWare 4 documents in your system. The quickest check is to look at your logical disks in the file system. DocuWare 4 disks have a three digit extension where as DocuWare 5 has a 6 digit extension:
DocuWare 4 = AAAAAAAA.nnn
DocuWare 5 = AAAAAAAA.nnnnnn
