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

  • The extension name does not matter in Linux. That is just for us humans to see what the file represents. If you have a program that can view a compressed tar file (ie. that would be with the "tar tvfz" command) software can open it. They tend to hook into the command itself.

Yes you can.

.tgz is the same as .tar.gz, just like .jpg and .jpeg represent the same file extension.

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 .tgz and .foo:

$ 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.
