This is a 1996 CD-Rom from Action Ware, It contains 1600 wads for Doom II along with some sound add-ons, patches, cheats and other files, File was repeatedly flagged by my AVG Anti-Virus as a trojan horse but I have tested it many many times to ensure it's safe. This file comes from Archive.org and It is not by me, nor do I own the CD either.
