MHUGHES  I've used this since it first appeared & have never had any problem at all. I rely on it.

To the reviewer who wanted to know what a valid administrative password is (!), it's the password you use to install any of your apps.

RMENDES  I never had a file on Trash that wouldn't go away by selecting Finder's 'Secure Empty Trash' option.

AGENTTWEETY  The program asks me for a valid admin password. Does anyone know what it is?

Thanks.

GTMP  Trash It doesn't work. I have had the irritating stubborn untrashable file but some how managed to shift it. There is loads of advice and good freeware to shift files when they're already in the trash, easy! But, I needed something to shift a doc "in use by an application" off my desktop, this wee app. said it could do it...nope.

Now here's a thing! I've still to get my head under the bonnet with Terminal but pride myself in lateral solutions to everyday mac problems. This is my top tip, (although this does need a second mac, I was already set up for this), network an other mac to your machine with the stubborn doc. Find your way to the desktop or folder containing the doc and trash it! You get a the satisfying words "..trashed immediately..", yes please. Bye Bye.

GAVIN CUTSHALL  Works exactly as advertised, free, and fills a major hold that Apple left in the system (even in Leopard).

This one's on all my Macs.

SPACE2BURN  This software does not work (yes - a previous version used to) and is completely unnecessary. Hold down option while emptying the trash.... all locked files will be deleted.

SWEETDOUG  I've been a mac guy for since 1200 baud was quick. I don't have time to ferret out archane problems with apps and such especially under OS X. That's why I use a mac. I'm just getting into X, as the previous systems have done all I required with apps. I want to be able to sit down, run the utility and be done with it. Having problems deleting files in the trash (Hello? Why IS this a problem?) lead me Trash It. I downloaded it, ran it, and it kacked. I see by the review that 3.5 seems to work.

Back to the drawing board, boys.

The OS are getting complicated, which is why software should be written for users that is brainless, especially for OSX.

JSJMCJM1  Trashit 3.6.1 did not delete {"Just Delete"} a folder in trash named Coby MP-C440 which has over 200 identically named folders nested within. It seemed to run, presenting gui for password and messages on the progess window. After 15minutes it declared all done, but trash still contained the nested Coby folders. OSX Emtpty trash reports 234 items, runs a couple of minutes, but does not empty trash. Cannot rename them when they are not in trash. Info says size zero.

SPUNKBUBBLE  I downloaded TrashIt, as i have 2 files in my trash that are locked and wont delete. I thought this tool might help, but when i move my files out of the trash to the desktop, they just duplicate themselves, i use the trashit tool, but im still left with the locked files in my trash. Can anyone help?

FINDING MYSELF USING TERMINAL  Nothing against the script, but if one has many problems with deleting files, a voyage into the basics of the Terminal are probably going to be necessary.

There are also dashboard widgets to allow entry of terminal commands.
