Legend
+ - New program tested
# - DOS program that was run in a Windows98 DOS box
* - Windows 32bit program (95/98/NT)
B - Best compression (smallest compressed file)
F - Fastest compression time
Q - Quickest extraction time
O - Best overall (smallest overall score - calculated by adding compress time, extract time, and time it would take to transfer the compressed file over a 28,800bps network)
+TAR - means that the test files were stored together in one TAR file first and then compressed.
