Let's say I have Explorer open with the folder tree structure in the left-hand pane, and the subfolders and files in the right-hand pane.

Is there a way that I can see the number of files under the folder, and the total size of all data in the subfolder in the right-hand pane?

  • I would like to see this as well. You figured they would have built into Windows by now... If you are willing to spend for that feature take a look at zabkat.com/x2facts.htm

  • Unfortunately it is not a plugin but it supposedly shows directory sizes freecommander.com/fc_details_en.htm

    It's not builtin, because all the current methods are not only inaccurate, but they are also IO intensive, considering it is a task users rarely use. Best left up to third party programs.

I use FolderSize on a server at work to administrate more effectively. It's essentially a Windows Explorer plugin that allows you to display folder-children, both files and folders along with their size.

  • But what about file count of each subfolder?

    Due to the age of this answer, there may be something better available now. I recommend you open a new question with that question.

This isn't possible using the default Windows Explorer, you would need some sort of plugin that aggregates this information (or check them manually). You can, however, get this information from a Command Shell (albeit not in a pretty way) via "dir /S". Run "dir /?" for other options. For example:

C:\Users\Josh\Temp\apache-ant-1.8.1>dir /S
 Volume in drive C has no label.
 Volume Serial Number is D819-69BC

  • There is DIRUSE.EXE as well, which does the job a lot better. I think I must have got it from the Windows Server 200 or 2003 Resource Kit.

  • DIRUSE is not available for versions of Windows after Server 2003.

For anyone else who may stumble on this question and need an answer - DU from sysinternals

Similar in usage to the unix utility.

  • I love DU but the OP wanted something that would work in his Explorer display (or I presume an Explorer-like display). DU produces text only.

  • This is exactly the best convenient tool for list no. of filer per subfolder under a folder with certain depth on Windows.

  • However, it doesn't support list list file in differnt size unit. It only supports kb.

  • It doesn't support list no. of files and size of each subfolder in the mean time. Kinda pitty.

This is actually really easy.

Right-click the folder, select "Properties" and you will see the information you want on the first tab "General" following "Contains."

This is really easy to do!
