Getting rid of fonts...

To speed up all the functions that a bunch of fonts slow down, I removed about 90% from the font folder in the Control Panel to a new folder on my desktop. But, somehow I feel I did not really do anything because they still exist on my computer. I should delete them completely, I think! Or, move them out onto a floppy or CD if I want to have them handy. Am I right? Should I get them out altogether? philav
