HDCleanUp has been discontinued
Email me when discounted: 
HDCleanUp is a disk utility that does the following tasks:
  • Application Uninstall. Simply drop an application onto the window, and HDCleanUp shows you a best-guess of all the application's related files. Move them to the Trash (except for the app; that's an Apple restriction) with a click of the mouse.
  • Orphaned Preferences Files. Ever download and try out an application only to quickly delete it? This function not only shows you a best-guess of orphaned preference files, but also of all the applications and their preferences files. This makes it easy to see what you can delete, and what to keep.

I’d love to try this app because it seems to be exactly what I’m looking for. But since this developer (Modesitt Software) gives no option for test driving it (it’s CrApp Store only), forget about it.

I’m inclined to boycott all developers who distribute their wares only via the CrApp Store.

So in thanks for my purchasing HDCleanup right before it went App Store Only—Bill at Modesitt is refusing to upgrade me. Nice.

Ignore my positive review, below—I can't review the current release. Duh.

I refuse to purchase site unseen. Please provide a demo that lasts at least 5 days; if I find it useful I'll gladly pay the purchase price. But without a demo, forget it.

This finds and makes it easy to deal with duplicates like nothing else I've tried (and, regrettably, paid for.) Good work!

This is the one to use if you want to clean out those unused/ delinquent preference files on your HD.

The only feature I was interested in HDCleanUp was the HFS compression option.

But it doesn't work!!!!

HDCleanUp goes through the motion of compressing something, moving the old copy to the trash and reports the savings. Drag the same file again onto HDCleanUp and it repeats everything again. But it never compressed anything either attempt.

If I compress the file with Terminal and then try to use HDCleanUp to compress it again it finally reports it cannot compress because it already is and there would be no savings.

Thanks for the great tool and I hope you can fix this annoying problem.

why dont spend a few weeks just thinking about what should be this application
implementing all you think is usefull and then.. once done
post the final release?
an update every 2 days becomes a real pita...

sure is I appreciate all your efforts to make it always better, but....

I personally don't see the problem with frequent updates. To me it shows a responsive developer. I'm not trying to start a flame war-just my opinion.


developer's taking ownership and responsibility.
that is money and far from annoying. bravo developa

The developer contacted me and immediately(!) added a preference for
searching either the main volume or all volumes (v 1.5). I tried it
and everything worked as advertized . I purchased the licence!

I tried the Application Uninstall feature but it seems as though HDCleanUP was searching, and searching.. and never completing. This was with the DEMO. As with other comments, I cannot bring myself to part with $10 to purchase when I cannot fully try the app.

What you can do is a time-limited on launch-limited demo.
