Go here for information on Tar and Gzip.

In a nutshell:
*tar.gz is like *.zip on windows. Yes you can download tar files via ftp.


Also:
*.tar.bz2 is pretty much the same as *tar.gz files.

Well, the tar file is an archive that contains all the files you packed into it. It does not compress anything. It just stores the files in one "container"-file. What you do with gzip is compress this container-file. That's why it is called .tar.gz. It is a tar file (.tar) that is compressed with gzip (.gz) or bzip2 (.bz2).

It's as simple as putting a few things (the files) into a box (the tar archive) and putting the hole box into a shrinker (gzip).

ok...thanx...but can i directly gzip a file or a folder without cretating a tar file?

You can compress files using the gzip command without tarring.

Although taring multiple files together often seems to reduce the file size when gzipped.
