Compress compare to other Zip programs?
for Two Small Files
2000 is designed to be the easiest to use, but this does
not cost you in speed and compression. It shares
the speed lead with other popular Zip tools. (Zip is a mature file format
and there isn't much of a speed or size
improvements to be made.)
Some users prefer
the RAR format (WinRAR) or the ACE format (WinACE)
because they do compress a little better than Zip –
about 1% to 7% in these tests. On the other
hand, they run much slower –
from 2 times to 5 times slower!
