Alice Dev Team has rolled out USBMate 1.0, an accelerator and optimizer application for Mac OS X 10.6 or higher. It costs US4.99 and is available worldwide through the Mac App Store in the Utilities category.

Featuring a file storage system optimization, USBMate was developed specifically to use for USB Flash drives, external hard disks and Flash memory cards. Features include the ability to erase temporary files left by Snow Leopard, Lion or Windows, along with a fully functional anti-virus program.

When you erase files, they’re only moved to the trash. The data itself isn’t erased. You can use USBMate and see how much free space you really have available.
