The 004 file extension is associated with several archivers or compression tools, which are using, or did use in the past, the 004 file extension for its multi-volume files or archives, such as Winrar (see part4.rar) or 7-Zip (see 7z.004).


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 004 file extension doesn't mean the first part of the multi-volume archive, but the fourth 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.
