Customer Reviews

It makes data management easy and fun.

The simple design and quick performance really makes this my go-to data management app. I work in video production, so with only 500 GB of hard drive space, I end up filling it up quick with files well over 10 GB in size. This app makes it easy to pinpoint the “culprits” and allows me to Open in Finder to either delete or down-convert to a smaller size. I wish they made the same thing for Windows because I use both Mac and Windows for my work, but from the quick scans to the list of the largest files to the easy-to-explore way it organizes data, this app seriously has transformed how I SEE data, and also how I manage it. So far this is my favorite app on the Appstore. If you need a great way to manage data, get this one. It’s awesome.

Very nice App, but help could be better

I really like this app. My only suggestion would be to beef up the help section as it is a bit sparse. For example, it is not clear from the discussion on “Collections” that that is what the “Drop Files” box on the bottom right is for. The section on Collections talks about dragging and dropping files, but it doesn’t even mention the “Drop Files” section at all. Maybe a couple of videos in the help section would be useful as well to demonstrate.

Finally I have some free space!

This has to be the first app that actually gets the job done. it shows a chart and long list of documents, organized by file size, to show what is really taking up your storage. Within 15 minutes, I deleted some old movies and large size game apps, and I saved 34GBs of space. As Wayne from Wayne's World would say "Excellent"!
