Want to see the size of your folders and not just files in your Windows XP Explorer listings?

If you are interested, Sequoia View is a very useful tool to do some nifty things with your folders. Other than that, this following note is now showing its age. If sorting and such is not necessary, a simple mouse-over your folders in Explorer will show you a tooltip with an approximate size of your directories. The menu option Tools --> Options --> View --> Show file size in folder tips should let you control the behavior of this tooltip.

Well it’s probably a simple feature that the Windows team at Microsoft forgot to include, so Mark Dormer has a solution. Just download his tiny DLL file:
Download Mark Dormer’s Folderview DLL

It’s an EXE file. All you really have to do is:

· Copy the file to your c:\windows\system32 folder.
· Execute the following command in Start —> Run dialogue box and you’re ready to roll:
Code:
regsvr32 c:\windows\system32\dirsize.dll
· Now open Explorer in details view, you wont see the column yet. Right click on a heading in the right pane and select “Folder Size”.

Couple of Cautions

· Calculating folder size is a turtle on very large folders with lots of subfolders. There’s no indexing built into this.
· As much you and I would like, this tool doesn’t do sorting of folders based on the folder size. You may want to give another utility a try, the Folder Shell Extension.

Couple of Tips

· To apply this setting for all the folder, click Tools, Folder Options. In the View tab and click Apply to all folders.
· To remove the feature, simply un-register the DLL later with the following command (ignore error messages if any) —
Code:
regsvr32 /u %Systemroot%\System32\Dirsize.dl
