In preparation for the nanoBundle, Macheist is offering mac app, Squeeze for FREE for a limited time. Offer expires March 2, 2010.

Squeeze is a background file compressor, which uses the new HFS-compression technology in Snow Leopard to transparently compress the folders you configure it to process. Mac OS will read those files normally, they will just take less disk space. Requires Snow Leopard 10.6.
