ULTGAMES  Really useful app. Fast and stable.

Emailed support with an issue that turned out to be user error and got an email back with the solution within 40 minutes. And this was at 10pm on a Sunday evening.

Highly recommended.  (Version 1.1.8)

DAREALGREG  Great support!

Had a problem with the tool bar on version 1.1.6 on Leopard. Developer had a work around within 15 minutes and a New version 1.1.7 is already being downloaded on this link. Get this application now with the discount. The ability to compare the results with past scans, including the hidden files and instantly see what files are growing, compress a file to create space, and reveal a files location in the finder. I know of no other application that does this.

Two years ago I had an invisable var file in the System Folder that grew to 68 gigs on my PB G4. Filled all the disk space and slowed system to a crawl. Took me hours to find it, this would have found it in minutes.

AND ITS FAST!

Scanned 146 gigs in 2.5 minutes on Alum iMac  (Version 1.1.6)

RAMPANCY  Baseline lacks the nifty radial view that WhatSize now has, but I like the look of their Tree View mode a lot more than GrandPerspective and Disk Inventory X.

Oh yes, and Baseline is much, much faster than any of them.   (Version 1.1.6)

MACMARIA  Very stable and when I tested it with other applications like WhatSize and OmniSweeper I found Baselines faster.

I enjoy the possibility of comparing the changes between the last measures (saved baselines) and the current one. Very handy.

The 20$ is a little bit too steep. I bought is during a promo and paied half price.  (Version 1.1.1)
