It would be nice to have an option that would allow to add more folders to be scanned for scripts.
Thanks for sharing your ideas, I appreciate it. I do not envision users having huge amounts of scripts that need to be organized into folders, so the script chooser only shows a single folder. Also, you can use Windows Explorer and just go to a folder and double-click a script there, you don't have to use the MyDefrag script chooser.
one could have them all in his/her "My Documents\MyDefrag Scripts\"
If you really want that then you could make a link in the MyDefrag folder to your personal scripts folder. I will not do that in MyDefrag because I feel that the current situation is better, clean and simple, all the MyDefrag files in one place.
