How to Check Folder Size in Windows
Sometimes we might get curious about how much the size of a certain folder really is. Some other times we might want to know which folder that occupies the most of the space within a drive, and then the curiosity moves on to the sizes of the files that belong to the folder.
We can know the size of a file instantly in Windows Explorer but not folder. Open up a folder and you can see immediately how much the size for each file is. To check a folder size, the most common way is to right-click it and select “Properties” from the context menu. The method can also be used to check the sizes of multiple folders. However, the size displayed is the total size of the folders. The “Properties” window doesn’t show us the size of each folder. This is where this Folder Size program comes in handy. More »

If you rely on what Windows originally provides, you can only view the size of one folder at a time through its properties. You can view the total size of multiple folders as well, but you cannot view how much the size of each folder at once. It is impossible to display folder size in Windows explorer as a column unless you use third-party application like Folder Size freeware.
