How to extract 001 files?

Most of the archived files that you can download have the following filenames: name.part01.rar, name.part02.rar, name.part03.rar etc. You can extract those files with WinRAR or the free program 7-Zip. But sometimes you will see files with the following filenames: name.001, name.002, name.003 etc, which I will call 001 files. In this tutorial you will learn how to extract these files. 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. Joining would be a better term for what we are about to do.

In this tutorial we will try to join the test.mp3 file that I made. 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.


We can do this with two different programs: 7-Zip or HJSplit. It is up to you to choose which program you would like to use for this task: 7-Zip or HJSplit.


Joining with 7-Zip

The free program 7-Zip is suitable for joining 001 files.

Download 7-Zip

Code:

http://www.7-zip.org/

After installing 7-Zip, right click on the first file (name.001) in the Windows Explorer and choose 'Extract here' in the 7-Zip submenu of the context menu. 7-Zip will extract the archive and place the extract files into the same directory as where the source files are located. You could also choose 'Open archive' to view the archive in 7-Zip or extract the file to another directory by choosing 'Extract files'. Easy!



Joining with HJSplit

There is a great chance that the person who posted the files used the program HJSplit to split the file to create 001 files. This freeware program is also able to join 001 files.

Download HJSplit

Code:

http://www.freebyte.com/hjsplit/

You do not have to install HJSplit. Just extract the 'hjsplit.zip' and double click on HJSplit.exe to start HJSplit. The main window of HJSplit appears. Since we want to join the files, click on 'Join':



Click on 'Input file' in the new window:



In the new window select the first file of the files that we would like to join, so test.mp3.001 in this case, and click on 'Open' after that.



Click on 'Start':



Now HJSplit will join the file. When it is finished you will see this message:



The files have been successfully joined!

I hope this helps all those ppl who keep asking me how to extract 001 files - Rashy
