friends isnt it boring that all folders in windows appear as boring yellow icon.so here are some tips to change that.

1: first create a text file name it as desktop.ini.
2:write the following thing inside the icon
[ShellClassInfo]
ICONFILE=c:\icons\abc.ico  (actual path of your image and image must be an icon (.icon extension)  file)

3:save this file inside the folder.

4:Dont forget to change the attributes of image to ReadOnly and Hidden to prevent any accidental damage.
