Why you won't find such software on Windows 10 App Store
Apps from Windows 10 App Store are limited in what they can do with the file system. They don't have the permission. ShowSize needs to scan all the folders to produce disk space reports. It can not be an App Store app. So instead of wasting time on the App Store to find such software, please download the trial and start using ShowSize which is a regular Desktop App.
The Trial has all the features, quickly installs and supports Windows 10 / 8 / 7.
What you can do with Folder Sizes list?
Selecting folders to fit a certain size: If I select many folders in this list by Ctrl-Click, a popup (like the one above) appears and shows me the added up size of these folders. This can be useful, for example, to find which folders will fit on a CD.
Whenever you need more disk space, you can use this list to identify the large folders. If you happen to recognize a folder that you no longer use, you can remove that directly from the interface. You can take help of other lists too, given below.
Keep your drives junk free. Get that nice "organized" feeling that you are in control of your disk space.
Install this list on the right-click menu of Windows File Manager so that you can start ShowSize quickly from there to show this list.
Print this list easily.
ShowSize has other useful lists too. Please get the details from the Home page.

"I searched on Google. Yours was the third one I downloaded and tried but the only one which really does what I was looking for. It's amazing that something so simple in concept was so hard to find, but I am very pleased with Showsize." David Lapish
"Your program is saving me a ton of time and the ownership information is invaluable to me! The latest version with that optional "owner" and "modified" columns are exactly what we needed! It's also very cool to work with a program that when you hit cancel on a long running operation with over 300,000 entries, that it actually works! The program is great!" William Devlin
"ShowSize is a real top-notch, well-written, and extremely useable utility. You did a great job on it! I use it quite frequently and the integration with Windows Explorer plus the various report views it gives make it that much more useful." George Lunsford
"ShowSize is a slick program and runs even faster than I would have thought it could -- it was a great help recently when I purchased a new system and realized how much data I accumulated since I switched." Neal Gresens
"I wish all vendors would respond as quickly and accurately as you have!" Andy Waszkiewicz

"Excellent program ... absolutely every option one could possibly think of!" Chris Goodliffe
