One drive unreal engine usage crash

Unreal engine 4 not connecting to content folder because it set itself to be opened through one drive and don’t have storage to store all the content needed

First: You need to have enough free space on your local disks to fit the engine and all the content of your project and all of the downloaded content from the marketplace. If you don’t have enough free space, you need to upgrade your internal storage.

Second: It usually doesn’t work right to try to put Unreal projects inside cloud storage mirrored drives, because the way that the compiler, and unreal editor, want to manage the files, clashes with the way that the cloud drives want to manage the files. If you want to create a backup, then set up a script that copies the project into the cloud drive folder occasionally. (This of course means you need even more free space on the drive.)
