The .gz extension means that the file was compressed using a program called gzip. It can be uncompressed by using either "gunzip" or "gzip -d", whichever is available on your machine. The .tar extension denotes that it is a tar archive file, which means that there are many files and/or directories inside. To extract, you must use "tar -xf". An example with filename "x.tar.gz" would be something like this: % gzip -d x.tar.gz % tar -xf x.tar I hope this helps. =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= asadal - 아/사/달 E-mail: asadal@karam.gsic.co.kr LG정보통신연구소 교환S/W실 Tel: 0343-50-7153 =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= P.S: 2002년 대한민국 붉은물결 붉은함성 월드컵 4강
