what's the old file format you miss most?

the board's new, so here's a plain question for whoever's up. which old file format do you miss most? mine's still the .NFO, the ascii header, the greets block at the bottom, the handle nobody could spell. you could tell who wrote it from the first line. what's yours? doesn't have to be a .NFO. a .ZIP with a README you actually read counts too :) keys and rumours can wait for another night.
