Disk Doctor: System Cleaner 4+

So simple to use and does exactly what you want..finds all the hidden stuff clogging up your computer memory and clears it off. So easy…well done really impressed.

Update
This used to work well, but I found an alternative that I preferred so stopped using it.
With the release of Disc Doctor Pro I thought I would use my original version again to decide whether to upgarde to Pro. It will no longer let me accept user files to analyse, so is unusable. I see from a review that the new Disk Doctor Pro has the same problem.

Original Review
I was hesitant to use any app that could delete files without me having total control. However, I have seen how quickly Application caches and logs can accumulate files that consume disc space, and how after a time they slow down my iMac.
Disk Doctor has received very good reviews so I decided to try it. I use it carefully, with a limited selection of disc locations.
So far I have found it works quickly, identifies large chunks of data that can be removed, and deletes them effectively. I have not experienced any problems after disc cleaning, and performance improves each time I run the app.
I have given it “only” four stars because I use it infrequently, so I may not have evaluated it fully. Also, like any utility, it is not exactly an exciting experience. Finally, although I have had no problems so far, I remain a little worried that one day Disk Doctor will delete something critical.

My previous review is below. However, Disk Doctor now doesn’t seem to be so hot. I ran a scan tonight. It told me that I had 240MB of files in the trash. Actually there were four files, total just under 60MB. I ran the delete process. It told me that it had deleted the trash, and now tells me that there are no files in the trash. However, the four files, total just under 60MB are still there. I closed and restarted Disk Doctor - no change. If it’s not telling the truth about these, what else is it not telling me?

Previous review:

I’ve been using Disc (UK!) Doctor for several months - I run it once every couple of weeks on my 2010 MBP. It has a clean, easy to use interface, and deletes the files it says it’s going to. Performance after a cleanup is always better.

What’s the definition of high quality? Give the customer what they want, when they want it, at a price they think is right. Job done.
