Working on project in different places

Thanks so much these are helpful comments.
How does WinRAR make a corruption obvious? I do always do check device and sometimes it finds problems and fixes them. It’s always only with Unreal files. Then when it says it fixes them they cause Unreal to crash or don’t show up etc…
That tutorial link worked for me. Thanks so much.
One thing I don’t get about the git version control - wouldn’t it be so much easier and cheaper for me as an individual to just get 1TB of dropbox? It automatically does 30 day version history…maybe that’s what I’ll do actually…?? Anyone do this?
