Windows 7 Tip: Quickly Find the Folder Size in the Folder Tooltip in Windows Explorer

12

Here is a quick tip that can be very useful and handy.

To quickly find out how big the size of a particularly folder is, simply hover over your cursor over to it in Windows Explorer. A tooltip will popup which contains information of how big this folder is.

Yes, no more right click and properties. But here is a catch. The real calculation takes up to 3 seconds to calculate the total size under the selected folder. If the calculation hasn’t finished after 3 seconds, Explorer will just give up and reports the size as “larger than X” where X was the size it managed to calculate within that 3 seconds.

You probably will wonder such process will slow down the overall user experience, especially on a slower old machine. And yes, you can disable such behavior by  unchecking the box “Display file size information in folder tips” from Folder Options if the performance bothers you or such information doesn’t help you greatly.

  1. You can select the folder,
    Right click,
    Select properties
    It will display the folder’s size – even if it takes more than 3 seconds

    This gets tiring after a few directories
    I prefer to use a tool instead
