Watsonville, CA – April 30, 2001- Driving towards development of a
universal compression solution for all computing platforms and file types,

StuffIt(tm) its award-winning, powerful compression technology , and
StuffIt Expander, a decompression utility, for Linux(R), including the

“In this ‘information age’ businesses and consumers are challenged with
sending and receiving files that come in a myriad of formats and from a
variety of platforms,” said David Polzine, StuffIt Linux/Unix product
manager. “At Aladdin we recognize the growing role being played by Linux
and Solaris, in the global exchange of information and believe StuffIt
technology gives users a powerful tool to aid in this exchange.”

StuffIt is the industry leader in cross-platform multi-format file
compression. Wherever there is a need for compressing large files into
smaller archives, whether to fit them on removable media, posting them to a
web site, or sending them via email, or storing them on a server, StuffIt
is the solution. On the other side, when downloading files from the
Internet or receiving files via email, StuffIt gives users the power to
expand and access any file type they receive.
