How To Show Folder Size In Windows

Quick Solution

Right-click on the folder and click “Properties.” Here, you will see the complete size of the folder. However, this method is not the best one if the folder size is too large. You can also use “dir /s [PathToFolder]” in Command Prompt to instantly get the size of any folder.

Your system may become very slow in performance, as the space in your disk fills up with all your files and programs. It would be helpful to know which folder is what size, so you can delete unwanted content from that particular folder to free up some space.

Unfortunately, Windows File Explorer does not show the folder sizes. Only file size information is shown when the View is set to Detailed under the File Explorer options.

There are a few methods to display folder size inside File Explorer, and other methods to view it too.

There are also a few ways to view the sizes of each folder, so you know which folder consumes the most space on your disk. There are also some utility programs as well through which we can check the folder size.

In this article, we will discuss some native ways, as well as third-party programs, through which you can easily check folder size in bulk.

View Folder Size in File Explorer

There are two methods for showing folder size in Windows Explorer natively, without having to use a third-party application.

By Hovering

One way to check the folder size in Explorer is to open File Explorer and hover your mouse pointer over the folder you want to get the size of. If you hover for a few seconds, it will open a small tooltip where you can see the folder size, among other information.

If you do not find the Size information in the snippet, the option has likely been turned off. Follow the steps below to enable it:

  1. Open File Explorer, click the ellipses (3 dots) from the top, and then click “Options.”

    Open Explorer options
    Open Explorer options
  2. Switch to the View tab and then check the box next to “Display file size information in folder tips” under Advanced Settings. Then click Apply and Ok.

You should now be able to see the folder’s size by hovering over it, as in the image below.

Through Folder Properties

Another way to know the folder size is to right-click on the folder and select “Properties.” Although this is not the most convenient way, it is still possible without a third-party app.

Right-click on the folder and click “Properties” from the context menu. The open window will display folder properties that include folder size, the size of the folder on the disk, the number of sub-folders and files inside the folder, its creation date, and other attributes. You can now see the “Size” of the folder it takes up on your disk.

Both methods tell the size of a folder. However, this only shows the size of one folder at a time.

View Folder Size using Command Prompt

You can also view the size of a folder using the Command Prompt. Here is how:

  1. Launch an elevated Command Prompt.

  2. Use the following cmdlet to display the size of the folder (in bytes) while replacing [PathToFolder] with the complete path of the folder:

    dir /s [PathToFolder]
    View folder size using Command Prompt
    View folder size using Command Prompt

Alternatively, you can also use the CD cmdlet to change the directory to the folder you want to know the size of, and then run the command “dir” to view its size. The results will be similar to the one we have discussed above.

View Folder Size using Windows PowerShell

Alternatively, you can also find the size of a folder using a PowerShell script. Of course, you will first need to allow running scripts within PowerShell. Click on the link to learn how, and then use the following steps to view any folder’s size in PowerShell:

  1. Run an elevated PowerShell instance.

  2. Change the directory to the folder of which you want to view the size using this cmdlet:

    CD [PathToFolder]
    Change directory in PowerShell
    Change directory in PowerShell
  3. Now copy and paste the following script in Powershell and hit Enter.

    switch((ls -r|measure -sum Length).Sum) {
     {$_ -gt 1GB} {
         '{0:0.0} GiB' -f ($_/1GB)
       {$_ -gt 1MB} {
         '{0:0.0} MiB' -f ($_/1MB)
       {$_ -gt 1KB} {
         '{0:0.0} KiB' -f ($_/1KB)
       default { "$_ bytes" }

The script used in the method above will automatically convert the size of the folder into GBs, MBs, or KBs – whichever seems appropriate to the script.

Frequently Asked Questions (FAQs)

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.
