What kind of files?

For contacts, I export all to the sim/sd card

For everything on my phone that can be seen by a computer I save it in a temporary file on my computer and drop it onto my new phone.

As for apps, I log into google and have them all redownload (does notnsave your info unless it was on the "cloud" or whatever they call it)
