This one was fun. I hadn’t ever played around with recovering deleted files.
There used to be a bunch of animals here, what did Dr. Xernon do to them?
This level starts off with the file animals.dd.
A few things I checked on. It looks like this is a disk image. I mounted the image and there are 4 files, but nothing that would indicate a flag or anything.
I knew that .dd files were used in disk images, and a quick search lead me to some software called ‘testdisk’
From here you select the directory you want to save the recovered file to.
