As far as I know, there are 3 ways to check Windows directory size. Now, I share them to you.

Method 1



Right-click on a directory in Windows Explorer, and then select “Properties” command, refer to below screenshot to know how to check directory size in Windows intuitively:
Check Windows Directory Size Method 1

Method 2



Move your mouse on a directory in Windows Explorer, wait a moment, you will see the tooltip, and the tooltip contains the directory size information, like this:
Check Windows Directory Size Method 2

But above two methods are very hard to check all directories sizes under a directory or a drive, and cannot sort directories by their sizes. So I will focus on the method 3 – it can check Windows directory size easier, automatically lists the size of all directories (and files) directly, and sorts directories (and files) with size in descending order (from big to small) by default.

Method 3

This is not all, you can do some common actions for the selected resource (left tree) or the checked resources (right list), such as Delete, Move to Recycle Bin, Rename, Run/Open, etc. Even more, you can copy the full path (e.g. D:\Test\NewDoc.txt) to clipboard. Just use the related toolbar buttons to do these.

Every button has tooltip, understandable icon, and corresponding context menu item. No need to learn how to use 1Tree Pro, just download, install and run it, you will get a tool to check directory size for windows in a tree viewer conveniently.
