Why doesn’t Windows show folder size?

From the very beginning, Windows Explorer has been unable to display a folder’s size in a dedicated column as an attribute. Although the individual item’s sizes can be seen, this is a feature many Windows users find lacking in Windows. Thankfully, you can view the sizes of folders using third-party apps like WinDirStat, Folder Size, TreeSize, etc.

How can I check multiple folder sizes in Windows?

You can check the size of multiple folders at the same time by either holding down the right-click of the mouse and selecting multiple folders or holding down the CTRL button and selecting multiple folders using the left-click from the mouse. Once selected, right-click the folders and click Properties from the context menu. The Properties window will now display the accumulated size of all the selected folders.

Is it possible to show file size in MB in Windows Explorer?

Unfortunately, no. Windows Explorer will always show the file size in the smallest possible form, which is in KBs, or KiloBytes. If you would like to view the information in MB or GB, you will need to use a third-party application for it, such as WinDirStat.

Closing Words
