Indeed, but calling TAR an archive is a misnomer.
Its a streaming protocol intended for use with tapes, not 'direct access, random
seek' devices like disk files.

Recall the issue: a backup is not an archive.

Yes, if you have a TAR file on a disk (compressed or not) you can use a tool - I
use Konkeror - to open it up and at a application level read through the whole
stream and construct that index, but that index, that image of the file as a
file system hierarchy, is in the application, not in the file itself.

TAR is NOT an archive format.
