Does anyone here know how to change ALL the folder icons at the same time? Like, i would like it so that when its a folder, that icon that i chose before will be used instead of the plain blue one.. I know you can do it with software, but is it possible to do it without software( i really dont want background programs running)

the easiest way is to use a program like CandyBar. CandyBar doesn't run in the background, but instead the desired icons are copied into the resources of applications (CandyBar makes a backup of originals so you can change them back to what you started out with). It's incredibly easy to use (simple drag and drop) and doesn't use up any system resource at all.

CandyBar comes to mind... see post #2

It's really as easy as it gets...

Another vote for Candy bar!
