Additional FAQs

How Do You View a Folder’s True Size?

To view the actual folder size, you can use a du Tool such as Microsoft Sysinternals. The tool returns the true folder size because it doesn’t double count files that have multiple hard links. There are also other additional tools to help you view the true size of a folder. These tools also provide intuitive size representation. Some show a graph, others show a pie chart or bars.

Why Do Folders Not Show True Size?

In most cases, a folder can take up more space on disk than its actual size. This is because the files in the folder take up space in the “Filesystems table” where their name and properties are stored. Though the difference is not usually much, when a folder contains several files, this can add up to a lot of space.

On folder “Properties” it is possible to see the difference in folder size by comparing the “Size” and “Size on disk” in the property dialogue box in Windows Explorer. Other reasons why folders do not show true size are:

• Hidden files – There might be hidden files in the folder that add to the size. In the file explorer options, ensure that the “Show hidden Files” option is enabled.

• Disk compression is enabled – If compression is enabled, it causes the total size on the disk to be smaller than the actual folder size.

• Content indexing – Content indexing in file explorer makes can take up space so the tree folder size will not be shown.

How Do You Show Hidden Folders?

• Select “View” Followed by “Options” then “Change folder and search options.”

• Go to the “View” tab.

• In the “Advanced Settings”, click on “Show hidden files, folders, and drives.”

• Click “OK.”

The hidden folders will now appear in File Explorer on your PC.
