SPIKEYMIKEY  Just found this app today - and have trashed 10 gig of rubbish. Great app to quickly finding stuff that you don't need anymore or can happily move off to an external drive. Much prefer the simple text view rather than a fancy graphic representation. Easy to understand and, quite quick on my 2006 core duo MacBook Pro - worth having for those moments of fast de-cluttering.

HARV  From Omni's web site, this release (only): "Updated the French help localization".

I suppose most won't need this, but I installed it anyway because ya just never know what other nits/fixes are included.

FWIW, I noticed no changes. It just works as it always had. Merci beaucoup.

PENGUIRL  OmniDiskSweeper is still the most functional disk sizer for my needs. The text display is far more useful to me than the admittedly prettier graphical displays and the built in delete function is a must have. The only thing I can think of that would make it more useful for me would be a list of drives and top level folders on the left similar to the Finder display.

DON MORRIS  If you simply need to know what's taking up space on your disk, and you don't need a fancy chart to display it, OmniDiskSweeper is the app to use. It's free, Leopard and Intel compatible, and reasonably quick.

THUS.SPAKE.Z  Works just fine on my late '08 Macbook Pro core 2 duo. OmniDisksweeper does the job quite well and is now free. Go for it; it's a no brainer. I bought it several years ago and have used it many times without issues.  
(Version 1.7)

AKROBAT  Used to be a good app. But now virtually unusable as it constantly crashes on my Intel Macbook.

Ok on my PPC.  
(Version 1.6.1b2)

GORDON142  Well, WhatSize has a nicer interface, but DiskSweeper lets you use basically all its functions without registering, which means its still my tool of choice. Honestly, $7 is about the upper limit for an application of this type, I think, but everyone wants more…  
(Version 1.6.1b1)

SYHARRIS  OmniDiskSweeper works just fine, but I'd say WhatSize is really just as good....and it's free.

Don't know if WhatSize works with Leopard(yet).....I'm still using Tiger.

But give both a spin, and then decide if ODS is worth purchasing.  
(Version 1.6)

E_COMMERCE  I love the company, but they seriously need to offer more if they expect people to pay for this, given that their competition does the same thing for free. What does it do that WhatSize doesn't? I certainly don't see anything at first or second glance.  
(Version 1.5)

ANONYMOUS  Another vote for WhatSize, absolutely free. You can find it at www.id-design.com. Alternatively, Tiger users can create a simple Smart Folder with a few rules to immediately identify the big files ... :-)
