Similar plugin from MVP Mark Dormer should accomplish what you wanted.

* Unregister the existing dirsize.dll plugin.
* Download the dll from the above site, and register it.
* Set the folder to detail view, and select the "Folder size" column
Note: Press CTRL and + keys together to auto-size the column width. Optionally, you can apply the settings to all the folders using "Apply to all folders" using the Folder Options dialog.

I'm asking because I just installed a dirsize.dll from
<
http://www.codeproject.com/shell/DirectorySize.asp> that shows
the size of each folder in detail view. I never noticed that
the file sizes were in KB's before. Obviously, folders are MUCH
larger and you end up with 9-10 digit numbers for folder sizes.
Some programs allow you the prefrence to show KB's or MB's as
dictated by the size. I thought maybe a registry entry may be
available.
Wow, new request for me.
