This is on Windows XP. I just found out I have a directory called Admin on d:\ which is not visible with Explorer, only through command line. It lists its contents as:

 Directory of D:\Admin

11/25/2008  12:31 PM    <DIR>          DiskImages
10/30/2002  10:39 AM    <DIR>          Drivers
11/25/2008  01:00 PM    <DIR>          Images
03/05/2003  05:03 PM    <DIR>          RUN
11/25/2008  12:31 PM    <DIR>          Scripts
11/25/2008  12:31 PM    <DIR>          Tools_dos
11/25/2008  12:31 PM    <DIR>          Tools_w32

Now D:\Admin\Images\25Nov08.sna is a 3.2GB file, which I'd like to delete if it has no function. Any idea what it is? Most of the websites I looked at listed the .sna file extension as belonging to Drive SnapShot, but I've never used it.

Is this on a Dell or HP machine? I would not be surprised if this is a recovery image for your machine. – Mokubai Dec 27 '12 at 9:00
Nope, it's a Compaq. – Johnny Dec 27 '12 at 10:44
That entire folder looks like a recovery indeed. But it's weird they didn't create a separate partition for that, which they usually do. – Matthias Dec 27 '12 at 11:02
You can always try renaming, rather than deleting, the folder and seeing if anything breaks. You might also take a look at the file in the Scripts folder and see if you can figure-out what they do. – martineau Dec 27 '12 at 13:21
Given its size, it could be a Drive SnapShot disk image file. – martineau Dec 27 '12 at 13:26
