ADSPROF is required. It stands for ADagio System PROFile.
EZSEMTAB contains record and file locking formation. Just leave it. . If deleted, Adagio recreates it.
I think EZSSILCK is used to control access to data from Crystal Reports for Adagio, at least some of the time.
Files with the extension LD4 are old ACCPAC program files. For safety, copy them to another folder before deleting.
If there are only two files with extension of COA and 375, they obviously are not a full set of data. Copy them to another folder and then delete them.
BTW, copying your data and experimenting on the copy si
exactly the right way to go. Paranoia is sometimes a good thing.
