I am using Ubuntu on WSL, which I downloaded a few months ago. However, my storage space on my local SSD (only 256 GB) filled up very quickly. I now have a 2TB external SSD, to which I would like to move my files. I want to be able to use WSL locally still, but just move the large amount of data I have on my local drive to my external SSD.
I tried downloading my /home folder of Ubuntu as a .tar file, moving it over to the D: drive, and then unpacking it. However, now when I try and do nearly anything in my original instance of Ubuntu it will not work. I have tried downloading a separate instance of Ubuntu, and that works fine (but has no files in it because it is a new instance). However, my original instance no longer works.
So, what I know is that I have a copy of all the data I care about (the /home dir which has been moved to the D: drive). I am willing to do a fresh instance if that is what's best. But, I am looking forward here: What is the best way (essentially what would a very experienced WSL user do) to have these two separate instances?
