Period. *Nothing* really can, given that not all UNIX machines which could transfer files to your machine have "cpio" or some other file-bundler capable of bundling entire directory trees. What if I want to send a large directory full of files via UUCP (if PC/IX doesn't have UUCP, this doesn't apply, but the question "why doesn't it have UUCP" would come up) from a machine which doesn't have "cpio" (a V7/BSD system with only a V7/32V license)? The easiest way to do it is to build a "tar" file, ship the "tar" file over, and un-"tar" it at the receiving end. It's an *extremely* common operation around here, and at other sites I've seen. Just because the machine doesn't have a tape drive doesn't mean "tar" is useless. Guy Harris {seismo,ihnp4,allegra}!rlgvax!guy
