The general file sequence is 001, 002, 003, etc.. and you will need all parts of the multi-volume archive to successfully extract the content.

In some cases, the 001 file extension doesn't mean the first part of the multi-volume archive, but the first part of split file. The first thing you have to do is to merge split files (001, 002, 003 etc.) in to one file (usually split archive) via split tools. Afterwards you can use a compression utility to extract data from the merge archive.
