I have been making snapshots of images for various things and just recently decided I no longer need the old snapshots. I went into virtualbox manager and for the image clicked on the snapshot optiona and found I had several listed. I really only want to save the very latest one so I decided to delete/merge the previous snapshots.
So before doing anything I had a snapshot struture like this:
- name 1
--- name 2
----- name 3
------- current state
I wanted to get rid of name1 and name2 snapshots which I did by choosing delete and then it says it will merge the data. So far so good as I now see what I wanted in vbox manager.
However, what I expected to happen on the disk was that it would clean up the Snapshots directory. When looking in that directory I see the following files:

Given that 3 of the 4 sav files are old are these still needed? Could they be deleted to save disk space or are they still used even though the date is not updated?
