Windows 7 - Folder Size in Windows Explorer

"Windows Explorer, by default, doesn’t show the size of the folder when you opt for the ‘Details’ view. This is one of the little things that users will find lacking in Windows Explorer."

I tried some 3rd party programs for this but, they didn't work with 7.

Anyone figure out how to display this information.

Hello Duckling,

Yeah, this has been removed since Vista. It has to do with how long it would take to calculate all of the folder sizes and displaying them in Windows Explorer. To see an example of this, right click on the C:\Windows folder and click on Properties. Take note on how long it takes to calculate just this one folder and all of it's subfolders in the boxed in red area of the screenshot below. Now, imagine that multiplied by how many folders that may be in a Windows Explorer window. It could give you a minute delay after before you would be able to anything in that Windows Explorer window.

This tutorial will show you a workaround for this using the pop-up description.

Alt + Enter is one option.

Folder Size for Windows 2.4
Known issues

• Doesn't work in 64-bit Windows, XP or Vista. I guess it needs to be built as a 64-bit DLL. But I don't have a 64-bit CPU yet. Anyone wanna donate me a 64-bit machine?
• Doesn't work on a substituted drive (for example, subst m: c:\stuff).
• Doesn't work with XDrive or WebDAV. Folder Size only works with files that can be accessed with a path name.
• Doesn't work on a substituted drive (for example, subst m: c:\stuff).
• Doesn't work with Vista.
• Someone reported some kind of conflict with 3D Studio Max.
• Someone reported that Explorer crashed after installing Folder Size.
• The service can use a lot of memory. The path names are stored inefficiently in memory. This is on the list for the next version.
• I think the automatic updating works for Windows shares, but not Linux Samba servers. There's no way to get it to manually update, so the cache becomes out-of-date. Need to do some debugging.
• All local users will see the full sizes of all local folders, even if they are denied permission to view their contents. The folder size service does the caching, and it runs with SYSTEM permissions, which can typically view every folder. You can deny SYSTEM permission to a folder to stop Folder Size from scanning it. Ideally, it would display different numbers for different users, depending on their permissions. Note that this is not a problem for network folders – the server computer lets you know what folders you have permission to see.
• It crashes when I log in with Remote Desktop and share folders.

Ah well. I did not look at the site very carefully.

Shoot

Maybe I'm missing it, but what version of Windows calculated folder sizes in details view? I haven't used details view much until Vista, XP is not giving sizes for folders. Also...I'm too lazy to install any VMs (98, 2000) at the moment...

Anyways its better to be left ondemand (properties) and not constant (details view), otherwise performance would take a hit.

Redux alert! But is there a way to view the folder sizes (details view) in Windows 7 64-bit? (not using the folder properties popup as that's singular and not practical when looking at 50+ folders, etc)

I've installed the latest folder size, service is running but doesn't seem to work.

Here are some free standalone workarounds. They'll work for occasional checking / maintenance and require a scan before working each time, but of course a built-in WE column would be best. Come on MS...
