OEM Folder Sizes 
-----------------------
OEM Size possibility?
Thought I would un-rar the OEM folder and sort by size, then remembered you can't! Found this link for sorting by FOLDER size:
http://foldersize.sourceforge.net/
Program adds Folder Size to Folders Detail view on your PC.
Now  unRAR and print a list of the folders in PPCGeeks_OEM.rar. Then at least there will be a list of which OEMs are huge and which are small.
