downloading again

[Toco.cx]

Hello, I played Hexxit a lot and I have an important question. It doesn't really have much to do with Hexxit, but w/ Technic launcher. So, my Laptop is shit and I gotta delete everything. I'm putting the stuff I wanna keep on my usb stick. If I download Technic Launcher again after that, will my worlds still be there? And if not, how can I put them on the stick?

Thanks for ur help
