How to extracting Multi-Part Zip Files with z01 extension

Introduction

Sometime it may be necessary for the client to send data in multi-part zip files. These can take different formats such as .tar files. In the case of windows based zip systems (e.g. WinRar) the multi-part zip files contain the file extensions <somefile.z01> , <somefile.z02> ... <somefile>.zip. These files then need to be extracted to work with the data within.

Procedure

To extract these files on a Linux system it is best to use 7zip, as it has built-in support for multi-part zip files. It is important to note that the file with the .z01 extension is the first part of the multi-part zip file. 

To begin extraction of a multi-part zip file:

1. Ensure all relevant zip files are within the same folder and then navigate to this folder. 

2. Run the following command: 7z x <somefile>.z01 

7zip will automatically find the rest of the relevant files and reconstruct the file in the same folder with the relevant file structure and extensions.
