Can someone help me how do i download my data file so i can move it to my new pc
Need some more info...what operating system are you using? In windows 10, if you type %appdata% into the search bar next to the windows logo at the bottom left, you can then locate the Mindustry folder. It will have all of your data. If you put that folder into the %appdata% folder on your new PC you should be able to pick up where you left off.
Hope that helps.

When you're in the game, go to settings and then game data. there will be an export option, select a folder and it will export all of your data + mods in a zip file.
On the new device you can go to the same settings page and then hit import and point it to the location of the zip, tada
