How to copy files in emergency mode

Hi all,

I have access to a standalone COS box that I got from work, but for unknown reasons I am only able to boot it in emergency mode.
This might be basics for the average developer, but I need to copy a file from it and I have no idea where to start.
I was able to browse to the file locally and I found it, but I could use some help with copying it.
I cannot access this box with WinSCP or PuTTy, because I am unable to boot it up normally and make the changes so I could access it from my home network.
I only have FAT32 USB sticks and NTFS external USB drives.

Please advice,

John

Ps.
I would have liked to boot it up normally so I could copy some more settings from it, but I gave up on that.
