Remember: Mac OS X 10.6/10.7 and Windows put temporary files and other junk in your USB Flash drive every time you use it. Launch USBMate each time before ejecting a USB Flash drive, and it will stay clean and secure! That's because only USBMate has a full-featured anti-virus program!
When you erase files from a USB Flash drive, they're only moved to the trash. The data itself isn't erased. Use USBMate and see how much free space is really left in your USB Flash drive.
It's one of the most practical utility apps to use every day with Mac OS X 10.6/10.7/10.8/10.9/10.10.
