Hi Timothy,

Would it be possible and desirable to (re-)implement Tarlz to use the

It is both possible and desirable. The 'posix' format is an extension on top of the 'ustar' format, so I plan to make tarlz use a "limited posix format"; 'ustar' where posible and 'posix' only on the files requiring it for any reason (long name, large size). This removes all limitations while remaining as compatible and simple as possible.

Would you be interested in expanding the features of Tarlz to make it a
more feature rich utility?

Sure. Suggestions are welcome. :-)

Here is where I got my info on the different tar formats:

Here you can find the specification of the 'ustar' and 'posix' (pax) formats:

Anyhow, whatever you decide to do is always best, of course; Tarlz is
already a really useful program, but I am just pointing out how it might be
more useful to me. :-)

Glad to know that tarlz is already useful to someone. :-)

Best regards,
