I just cleaned days ago over 800GB of data I did not needed anymore .
Each time you start new session everything is saved to it own folder .
That why when you are not happy with the scan , you click the restart button and not back button to scan new scan as it will create new session .
3D data can take lots of space
That why early phone users complained about and now we do not have any cache project data on the phones no more , so we have to fuse it on the phones , that was bad decision from Revopoint to change that .
I could just scan objects on the phone and fuse it later on PC , now I have to wait forever and fuse it each time on the phone , waste of time and battery .
So keep pushing the restart button in place of create new scan session to avoid clogging your HD with data you don’t need .
