Files with a .tgz extension, such as extension.tgz, are [tarball]s compressed with [gzip]. They can be extracted using tar by running gnu's tar command in this fashion: tar -zxvf extension.tgz If you don't have a Unix-like system or [Cygwin], you can still extract files from a tgz archive. WinZip may be able to handle them ''([DKF] - Yes it does...)''. Another program called QuickZip does gzip'ed files IIRC. Note: Netscape often will gunzip .tgz files without letting you know, so tar -xvf extension.tgz may be all that's needed. .tar.gz is used more commonly in some circles. Winrar can also handle tar and gz on windows. The [sdx] utility has some knowledge of tgz files, there's a "tgz2kit" conversion command, and "ratarx" which can be used to get rid of duplicate files (ratarx stands for "reverse actions of tar x"). See "sdx help tgz2kit" and "sdx help ratarx". [DKF]: The "''.tgz''" is a contraction of "''.tar.gz''" to deal with the limitations of old [DOS]/[Windows] systems. ---- Related: [tbz] [tarball] [gzip] [zip] ---- !!!!!! %| [Category File] |% !!!!!!
