How many versions of arduino have you got?
I've got a few versions of arduino on my pc and I'm probably wasting space but I bet I'm not the only one.
Just wondering what versions are best to keep. I believe there are incompatabilities with existing code for some older or newer versions.
At the moment I've got 21,22 and 23 and 1.0.3.
Are there any I haven't got I should have and which of these should I ditch.
Also is there a way to tell each version where it's sketchbook is and keep it. I've noticed that when I switch ide's I have to change the sketchbook back. Really annoying.
