Lost files

Hi guys,

My PC went down and I basically lost my mobile game I was developing for some time (had some backup copies but those are quite old, would take me days to get back where I was…) The thing is I have the “launch on mobile” version on my phone as I kept testing it on it, which unfortunately not starting properly when copying files to PC. So my question is there anything I can do to make it work when copying all files from mobile to pc? As well I noticed mobile files have standard “uasset” as well as “.uexp” copy for each file. What are those doing?
