1eyed: do you have access to the support website? If so, there is a putsy download you can use in the reference section to download the file definitions & the v7 version of "DRMs". Not like we had in v6, but something better than nothing. They list the cobol programs & the files opened in what mode by each program. If memory serves, I may have gone directly to the ftp site & downloaded w/ftp client software since the eSynergy download was slow & cumbersome while the ftp went pretty fast. You can use your pervasive tools such as butil & maintenance to get info about the file as well as opening the table up in pervasive db manager. This same type of tool is on your MSSQL client as well in enterprise manager & just by opening the table. If you can't get the info another way, I'll email you what I have downloaded over time if you leave your email address.
If your reseller (or you if you did it yourself) fully installed the macola help & techdocs files, you will find the filelo folder under technote & the file defintions should be included as well. If they aren't there, check your 103d update CD as that is when the most recent ddf changes were made.
