CYBERATOMIC  Who cares about what is keeping you... you just want to empty the trash and move on with your life.

A good tip to do just that, is to use the "Secure Empty Trash" option in the finder File menu options. This will do just that, empty the trash - without having to do anything like command line stuff, open a 3rd party app like this one, etc...

Keep in mind, this won't work for stuff that is truly still running as a root process, and it will take awhile for larger files trying to be trashed since it is writing 1s and 0s over that data...

But for a quick tip, it works nicely and you won't have to worry about whats keeping me or anyone else for that matter.

Cheers!

FRED3RIK  I don't know what the previous commenter did wrong, but for me, this thing worked flawlessly. Thanks a lot for making great freeware/donationware.

MACNERD1984  Didn't work for me whenever I tried it (3 times). After trashing it, it got stuck in the trash despite the image being ejected etc. and I had to use Onyx to get rid of it. Oh the irony...

PETER DA SILVA  I normally just use "sudo lsof | grep Trash"... but I gotta agree that's a great icon. :)

JROX  This is actually quite a handy app to have around. Many times ive been unable to find what's keeping me from emptying the trash. Kudos to the developer!

LARSEN2K4  Great!!!

This app just saves me a ton of time - I'm working with files a lot, and there's nothing more frustrating, than being unable to clean the trash, because of busy files.

Thanks a lot!
