A terminal error occured on my computer and I found myself unable to log in to Ubuntu. To remedy this, I decided to simply install it again on a partition and then access my saved files on the old partition from the new one, thereby losing only my software and settings. The problem is, I do not know how to retrieve those old files. There is an icon called "90 GB Filesystem" in Nautilus: it has 21 folders which hold which have exactly 1.7 GB of free space each and only system files in them.
The question here is: are my old saved files retrievable? Are they retrievable through "90 GB Filesystem" or some other means?
