Problem in unzipping the .tar.gz file

Friends,

I downloaded a source code for RH9 platform in .tar.gz format. I downloaded it with DAP in Window platform, copied to CD and then transferred to (copied) Linux (RH9) platform. When I tried to unzip the file by 'gunzip'/ 'unzip', it is showing that the file is not a zip archive or problem in unzipping and so........... What is the problem, can anybody help me ?? I downloaded the file of about 40MB size by a Dial up connection. Further, generally, the colour of a downloaded .tar.gz file is 'red' here (in linux platform), but this file is green in colour !!
So, I want suggestion from my friends.

hmm, try in command line:

Code:

---

tar -xzvf file_name.tar.gz

---

I know this may sound painful for someone on a dialup connection, but if the above suggestion doesn't work, try downloading the program without any download manager.
