Because many people have WinRAR installed on their PC, I will explain that program first. It is up to you to choose which program you would like to use for this task: WinRAR, 7-Zip or HJSplit. We can do this with three different programs: WinRAR, 7-Zip and HJSplit. As you can see in the image below this file is split into eight pieces that we have to join before we can listen to the test.mp3 file. In this tutorial we will try to join the test.mp3 file that I made. Joining would be a better term for what we are about to do. Extracting isn't the right name though: normally these files are not compressed like RAR files, but just split by a file splitter, without compression. In this howto (tutorial) you will learn how to extract these files.

But sometimes you will see files with the following filenames: name.001, name.002, name.003 etc, which I will call 001 files. You can extract those files with WinRAR or the free program 7-Zip. Most of the archived files that you can download from binary Usenet newsgroups have the following filenames:, , etc.
