Windows 7: Folder Size in Windows Explorer

Another option would be to use the portable, or installed, version of WinDirStat. It will give you an overview of all folders on a drive, and the space the consume. You can even alter the view to show by file type.

Nice one Deacon! It's the most similar to foldersize me thinks! (loving the fact that you can click the graph and jump to the next largest file, etc)

The best one I found was the great and free "Scanner 2" (works great on Windows 7 x32/x64)

It's very light and fast and you can see graphically what's taking up the most space and where...options to open/delete, etc.

foldersize was always a must install for me
i've been using overdisk Elias Fotinis OverDisk :: Visualize Folder Size Allocation since vista

ExplorerXP

I use it mainly for renaming batches of files linked to framemaker documents but it also displays folder sizes and allows for tabbed folder windows. It's working fine for me under win 7 pro 64bit.

...and the price is right =)

ExplorerXP - Freeware file manager for Win2K/XP

ExplorerXP is a very fast, small, compact and innovative FREEWARE (for non - commercial use) file manager for Windows 2000/XP. Unlike the regular Windows Explorer, it displays the total size of each folder and allows you to browse multiple folders from a tabbed interface.

There already is one. Hover over the folder for the tooltip or go to properties.

FreeCommander file manager can show folder sizes.

Note:
Window shown in horizontal split mode.
Vertical split mode can also be used.

have ether of you ever use a mac? well i want it to be like that. not some third party app or checking each folder...

A possible option would be to put an entry in "Desktop.ini", when you open the folder or save a file to a folder.
It could easily update that info whilst it's indexing.

Not since the original B/W Macintosh.

You'll have to complain about it (or suggest it) to MS during the Windows 8 Beta tests.

IMO, Window Explorer has always only been "adequate" for file management.

I only use FreeCommander when I want to do something "tricky", like mass file renaming.

When I need to check folder sizes, usually I'm thinking about what's using the most space. So a great utility I've been using for a long time now is "OverDisk" (it has a context menu option).



Great tool, and only when I need it.

Resuming one of the many posts I found about the topic for a question/proposal:
does it exist a Windows shell extension which allows displaying folder icons sized proportionally to folders sizes, rather than always same-sized icon per each folder?
I can't find anything like that for WindowsXP, and I didn't yet pass to 7. Shouldn't a modern OS be able to update in realtime the "index" of folder sizes and to resize icons in file manager accordingly?
"Modern" file managers have same aspect of Windows 3.11 file manager, with each icon the same size of the others!

If such a shell extension still does not exist... it's time to write it up! Aren't you bored of regularly scanning your HD with 3rd party SW to figure out in which sub-sub-sub-sub-subfolder you placed your 3 GB file?
