The Windows 10 file explorer has a lot of useful functions, but many of them aren’t too obvious. If you want to see the size of your folders, you have several options available to you. Here are some of the best:
If you want to see the size of your folders, you can actually do so just by hovering over a folder. Open your File Explorer to a random location and hover for a second or two over the folder in question.
You’ll see some additional info there, and part of that is the size of the folder!
Make Size visible
If you want to see your file sizes permanently, you can easily change a setting to make this possible. Open a file explorer window and right-click on the ‘Name’ field at the top. You’ll see some options – specifically, options, that let you pick what sort of info you want to see about your folders.
Select Size and the property will appear on the far right of your window.
Tip: While the size property will appear, it may sometimes be empty – Windows can’t always correctly estimate file sizes in that view, especially for folders that contain additional folders. Use one of the other methods if this one doesn’t work for you!
For the most detailed view of your folder sizes, you’ll have to use the Properties feature. To do so, right-click on a folder and select Properties at the bottom of the menu.
A new window will open up and show you some additional info on your folder.
You’ll see what size a folder is, if it is compressed, how much space it takes up on the disk (this is the size on disk property), and even how many other files and folders are in the folder.
Tip: Windows only looks into the actual folder, not sub-folders. So, if your folder contains two files and two folders, each with two files each, this view will still say two files and two folders. It doesn’t count the files in those folders into the total number of files, but it DOES count them into the folder size property of X MB, for example.
