vimdiff

Say I have unpacked a gz-compressed tar file, and do not remember what changes I made to the unpacked files, or I archived a folder a while ago and want to know what has changed to the files since.

I can use tar -zd to get an overview. Then, say it shows me file foo has changed. How can I see the changes in this file, i.e. the difference between the file on my file system and the (older) file in the archive (ideally in vimdiff, but diff output would be fine too)?
