I created .tgz archive via Total Commander on Windows, can I later open it on Ubuntu? And is it the same as .tar.gz? Thanks
Actually, a file extension has no meaning in Ubuntu. Ubuntu determines (at least should) a file's content by its MIME type, not by its extension. But .tgz and .tar.gz are used for the same purpose: To describe a gzip-compressed TAR archive.
As TAR is an open archive format, it can be read without problems on any system that supports it. Ubuntu does so - every .deb package is compressed as a gzipped TAR.
So unless you didn't apply any encryption etc., you shouldn't have any problems. If you're still not sure, boot Ubuntu into a live environment and find out.
Example: I copied a driver packed into a file ending in
.tar.gz into two other ones ending in
$ file DPO_RT3290_LinuxSTA_V2600_20120508.tar.gz DPO_RT3290_LinuxSTA_V2600_20120508.tar.gz: gzip compressed data, from Unix, last modified: Sat Oct 12 00:22:20 2013 $ cp DPO_RT3290_LinuxSTA_V2600_20120508.tar.gz DPO_RT3290_LinuxSTA_V2600_20120508.tgz && file DPO*tgz DPO_RT3290_LinuxSTA_V2600_20120508.tgz: gzip compressed data, from Unix, last modified: Sat Oct 12 00:22:20 2013 $ cp DPO_RT3290_LinuxSTA_V2600_20120508.tar.gz DPO_RT3290_LinuxSTA_V2600_20120508.foo && file DPO*foo DPO_RT3290_LinuxSTA_V2600_20120508.foo: gzip compressed data, from Unix, last modified: Sat Oct 12 00:22:20 2013
So as Shakespeare already wrote:
What's in a name? That which we call a rose By any other name would smell as sweet. - Romeo and Juliet, II,2:1f
Name doesn't matter, at least as long as you're not using Windows.
