I am going to post a trick, which many of you may be interested to know that how to change background of a Folder in Windows XP. After much Googling on this topic I’ve found two ways one is related to coding, so it is recommended to advanced users and the other way is by using a simple software which anyone can easily use.
I am posting the most convenient way over here. For this you need to get a software named SodaBush Windowpaper XP. It is a freeware and you can get from its official website. It requires .NET Framework 2. After getting this Software you can select the folder and change its background whatever you would like to have.
You can now be able to change from your old boring white background to your own custom Background. The background image can be bmp , gif or jpg.
