What exactly does lost+found do?
I've been running Linux for a while but this is such a noobular question I put it here.
I got a new hard drive, and installed Ubuntu on the new hard drive fresh. Then I wanted to migrate my /home directory to the new hard drive so my data and all my settings would get transferred over. I booted from the old hard drive, and now I'm fixing to copy my home/userN accounts over to the new hard drive's /home partition.
In my old /home directory, there was user1, user2, and lost+found.
I'm not sure what lost+found does or if I want to copy it over to the new hard drive or what.
