I'm using Windows 10, 64-bit Pro computer.

I want to download following Two files from internet to my hard disk:

filename.tar.bz2
filename.tar.gz

These Two files should contain 'c' source code.

What are these file types? Are they like zip files? If yes, how do I unzip them.

 

Hello,

The files are compressed .tar files, wich are often used on linux systems.
The .bz2 is the Bzip2 format and .gz is the gzip format.
On a windows system you can unpack them using 7-zip:
