FolderIcons is an MS Windows customizing tool, that helps you change the icons of your file system's folders. It works by simply adding a desktop.ini file in a folder, then changes the folder's attributes, as described in Microsoft's Customizing Folders with Desktop.ini MSDN article.

FolderIcons automates this process making it very easy to change your folders' iconds, revert them back to original, recursively asign the same icon to a whole folder tree, etc. Compatible with icons in DLLs, EXEs, ICLs and literaly any file that contains icons.
