Nova Media has updated UberMask (http://www.novamedia.de/index_e.html) for Mac OS X (10.6 and higher) to version 2.1. The upgrade adds compatibility with Mac OS X 10.7.2 and fixes some bugs.
UberMask hides files and folders with a keystroke from curious eyes and inadvertent discovery. Even Spotlight can’t find the files hidden by UberMask.
Version 2.1 now supports hiding files and folders on multiple volumes and partitions as well. It’s a free update for all current owners of a UberMask 1.x license. For new users the cost is approximately US$14. A demo version is available for download.
