Curb app for Mac dumps the trash from USB drives
This has always been a pretty straightforward process on your computer, but USB drives and removable media makes it a little trickier. When you delete a file from a flash drive, those fragments are actually stored on the device itself until deleted manually or when you delete your entire system trash. This isn't always the best method - especially if you want to let someone borrow your drive or want to free up some extra space.
That's where Curb comes in. It's a free application available for Mac from MRR Software that makes file removal a snap. Just drag your drive's icon onto Curb and it will find and delete those fragments and files you no longer wish to have. Curb comes with a variety of settings and secure methods to delete your files easily and safely. In my testing, Curb was great. A simple idea executed well, Curb got rid of a lot of the random unreadable files and text documents that were left after deleting some folders.
