ACT03-95.ZIP Archive Comparison Test A.C.T. is a monthly report comparing 29 compression programs (archivers) for speed and ability to compress files. The archivers are tested on TXT, EXE, 669, BMP and multiple files. It also includes a checklist of special features some archivers can perform and the e-mail addresses of the authors.
