Saving PS Actions.

I have several PS7 actions that I wish to save in a file to upload, so I can use them on my other computer. A couple are actions I've dled from various tutorials, most are my own. However I cannot find where they live in the PS folders. I assumed they'd just be in the Presets - Photoshop Actions folder, where they'd be named the various names I've given them and I'd be able to pop them into another file and upload that. However that doesn't seem to be the case, is it not possible to do this, or am I looking in the wrong place?
