I dont mean the key I mean the file with blockland in it. My dad wants to know if you can retrieve your add-ons and builds if the computer crashes. Thanks again
1) You don't need to be able to keep all your add-on because they will always be downloadable off either RTB or the forums.
2) For the saves, do this...
1. Locate your blockland folder
2. In there, there will be another folder called saves.
3. Copy that on a disc/SD card
4. That is now a back up of all the builds you have built before you copied it onto the disc/SD Card. Do this once a month to be safe.
