Smith Micro and Yosemite Technologies partner to bring FileKeeper Pro directly to consumers through popular retailers

Simple and Affordable File Protection and Recovery Software Solution Simplifies the Way Individual Users Protect and Manage their Data

Aliso Viejo and San Jose, CA — November 14, 2007 — Smith Micro Software, Inc. (NASDAQ: SMSI) Consumer and Compression Group and Yosemite Technologies, Inc. today announced a publishing agreement to offer FileKeeper Pro, a powerful yet simple and affordable file backup and version rollback software solution for laptop and desktop computers. Yosemite FileKeeper Pro is now available from Smith Micro's Web store at: my.smithmicro.com/win/filekeeper, popular retailers and catalogs, and distribution partners worldwide.

Sooner or later every individual and business will be confronted with some level of computer failure. The principal threat during a failure is typically corruption or loss of critical business or personal data, which is either irreplaceable or difficult and time consuming to recreate. With FileKeeper Pro, individual users at home or in the office can deter this common threat by implementing a straightforward data protection solution with intuitive features, including recovery of previous versions of a file or deleted files with a simple right click of their mouse in the Microsoft Windows user interface.

"Backing up documents, images, and system files is one of the most important things that any computer user can do," said Jonathan Kahn, Executive Vice President and General Manager of Compression and Consumer, Smith Micro Software, Inc. "Computers have become ingrained into our daily lives, so naturally there are things stored on our computers that can never be replaced if lost. From family photographs and stories, to business papers and tax documents, all irreplaceable data should be backed up with this simple, easy-to-use file backup software solution."

FileKeeper Pro uses near Continuous Data Protection (CDP) technology to protect valuable data as it is created and transparently stores file versions to one or more safe storage locations. File versions are automatically stored in a repository on a disk inside one's computer, allowing for the recovery of a file or version, even when the computer is not connected to external storage. Only the bytes that have changed in a new version of a file are stored, providing very efficient use of disk space. The files and changes are automatically saved to a secure storage location on a USB hard disk drive or networked storage when it's connected, ensuring the data is safe and always available even if the user's laptop is lost or stolen.

"Smith Micro has the deep industry expertise and the strong channel relationships that we were looking for to expand FileKeeper Pro's reach," said George Symons, CEO of Yosemite Technologies. "Broadening our distribution and getting the word out is a great way to encourage consumers to utilize data protection strategies."
