Your Mac is full. Disk Diag shows you what's taking the space and clears it out.
Huge files you forgot about, duplicate copies, caches, and leftovers from apps you deleted long ago — all in one app. And plenty more tools to free up storage space.

Out of sight, out of mind, so out with it!

I tend to go with the out of sight out of mind approach when it comes to files on my computer. If I haven’t touched it or thought about it for long enough that I’ve forgotten it’s there, chances are it’s not important enough to keep, and those are exactly the files that Disck Diag digs out of the netherworld. Mind you, it’s best to double check exactly what the app has signed up for the chopping block, but for the most part, the biggest things weighing down my Macbook Pro mid-2012 were useless email files and caches. Before using Disk Diag, I had a measly 28 G left of my 750 G hard drive. One click and maybe 5 minutes of waiting later, 4 years worth of useless junk was wiped away, and my free storage jumped up to around 260 G. A simple and efficient way to do a little (or a lot) of spring cleaning. Very happy that I bought this app.

I opened and used Disk Diagnosis to check for problems on my computer. Once it was done it listed various files and how much data was stored in them. However, my primary purpase was a diagnostic review to show if something was malfunctioing in some way, or otherwised compromised. Bur what it twlls me is: “THE APPLICATION HAS ALREADY COLLECTED INFORMATION ABOUT YOUR FILES. RECENT SCAN RESULT WILL BE LOST.” My problem with this response would be very different, if they first told me how to see the actual results of the scan; such as corrupt file, possible virus, or other problem that I really do not what to have. Maybe I am just missing the focus on this, in which case, it isn’t the app. I wanted to use - so it may be great for telling me how much data various (albeit not all identified areas 9e.g., Mail downloads, logs, brower data, iOS software updates). I suppose if that data awas what I needed — my only goal would be to forage through the contents and delete old or unwanted data that would be taking up unnecessary space. On the other hand th idea of just “delete files” is not somethign I would want to do, initially, becasue it may be data I really want to keep. THis is not so much a review, as it is the problem with what I hoped to use it for — identify problems (other than about of data) — and provide some methods of dealing with corrupt files, evidence of external hack or access, or some similar problem for which I cannot specify - other than - what are the problems — can the app fix it, if not what do I need to do. That’s why I gave it 3 stars - it may be an awesome app if I understood it.
SIMPLE, NO MUSS, NO FUSS, WORKS GREAT

Using any tool like Disk Diag involves a certain level of trust in what the program does and how it does it. You have turned your computer over to an unknown enitty, and then must hope/pray it does what it is supposed to do, does it well, without any 'funny business'. I've used Disk Diag on and off for a long time, it seems to be simple to use and effective in getting rid of 'stuff'.At this point, I trust it to work as advertised, and it seems to do that very well. As I say, no muss, fuss or bother. It is simply another tool to help keep my computers happy and healthy. And these days, that is no mean feat.

Don’t get me wrong, I love this application. It is super useful and I can really tell a difference after cleaning up space on my hard drive. I wish I could give this a 5-Star review, but there is only one problem with this. Every time I clean my hard drive, it deletes the iCloud Drive caches on my computer, therefore not allowing me to sync my documents to iCloud until I turn off iCloud Drive and restart my computer. I know one solution would be to just turn off deleting caches on my computer, but that is where most of my hard drive space is wasted. If there was any way to select specific files I wanted to delete, or make a way to not delete important application caches, I would absolutely change my review. Other than that, it works perfectly!
Developer Response
Thanks a lot for your detailed feedback. We've added the issue to our todo list!
Disk Diag 3 has been completely reimagined, with a new interface throughout and a brand-new disk mapping tool.
- Space Disk maps your entire drive as an interactive chart.
Click any slice to go deeper, select what you don't need, and clean it without leaving the map.
- Redesigned Dashboard puts every tool one click away, arranged the way you want.
Under the hood this release brings a long list of stability fixes and various refinements across the app.
We'd love to know your feedback about this brand-new version.
Feel free to contact us at http://www.rockysandstudio.com/
In case you have questions about updating from an earlier version, we'll be happy to help you out.
