System Utilities - Shredder

Description: You're familiar with them around the office - those loud devices that leave mountains of finely shredded paper in their wake. Now you can have the convenience and security of a digital document shredder right in your Dashboard; even better, its 100% silent and doesn't leave shredded bits about for you to clean up later. It's variable shred levels give you just the amount of protection you need.

Low: Bypass the trash can. Though this isn't as secure a deletion of your files, it is a quick way to get rid of those files you know you don't need, leaving the trash can for those things you just might want to dig out later.

Medium: Secure erase. This mode overwrites your shredded documents with a US Department of Defence compliant 7 pass procedure.

High: Virtual Paper Pulp. Use this setting for only the most sensetive files. Though it might be slow, the 35 pass Gutmann algorithm will ensure that no data from these files is ever recovered.

The digital document shredder is everything you need to feel secure while sitting in front of your Mac. And, with the upcoming release of Mac OSX 10.5 Leopard with Time Machine, this widget will step up to the task of making sure that not even travel backward through time can recover the data you want to permanently remove from your system. Be careful, though: shredding is total and permanent, and Interdimension Media assumes no responsibility for any loss of data that you may incur through its use (that's the point, though, right?). Just watch out; the desire to round up some digital scraps of paper just for the satisfaction of watching them shred to bits may overtake you.

To shred a document, click and drag a file from the Finder. Then use a hotkey (F12 by default) to call up Dashboard, keeping the document in hand. Drop it on the shredder to permanently erase it from your system.


1. Permanently and securely deletes your sensetive files
2. Three shred levels give you exactly the level of protection you need (see descriptions above)
3. Support for queueing multiple documents
4. Stunning graphics and smooth animation

From what I can tell, this appears to work great! A very neat and easy way to quickly shred individual files.

Would be nice if someone can confirm that it does give the level of security that it claims.

It even copes with the zips on zipped files and the pins on SketchUp files! smiley

Russel, it does in fact give the level of security it promises. The widget is actually a wrapper for the Unix based Secure Remove (srm) command, which you can find more about here:

And, just so you know, you can drop directories on it too.

I love the idea, and the graphics are amazing (especially the satisfying feeling you get seeing the documents get destroyed).
It seems to have a bad habit of wandering around my dashboard, for reasons I cannot explain, however.

I'm still using this regularly. I do get the same problem with the widget moving around the screen though.

After restarting my comp the widget has always moved a short distance up the screen? Unless I reposition it, it continues to move up with each restart.

Is it set to a specific screen resolution or something? I'm running 10.4.9 on a MacBook Pro.

Really useful, and I love the graphics (very satisfying watching my documents shred), but I have the same problem others have reported with the widget changing position every time I restart the computer.

Wherever it's placed originally, it seems to determined to creep up the screen and cuddle up to the widget above it.

If I move it back into position it stays put until the computer restarts, but it would be very nice not to have to do that each time.

I have the same problem running 10.4.9 on a Mac Pro, with a 30" Apple display and on a MacBook.
