What is a 004 file?

004 file extension used by various data archiving tools. The data archiving process allows users to create backups of important data in a compact, compressed form to reduce disk space usage.

004 file is the fourth part of multi-volume data archive. Multi-volume archives are used for dividing large data into smaller-sized parts. Such procedure allows fitting data on multiple storage devices of smaller size, such as CDs or DVDs. In order to unpack such archive, all its parts must be placed in the same file folder.

How to open 004 files

If you cannot open the 004 file on your computer - there may be several reasons. The first and most important reason (the most common) is the lack of a suitable software that supports 004 among those that are installed on your device.

A very simple way to solve this problem is to find and download the appropriate application. The first part of the task has already been done – the software supporting the 004 file can be found in the table. Now just download and install the appropriate application.

Possible problems with the 004 format files

The inability to open and operate the 004 file does not necessarily mean that you do not have an appropriate software installed on your computer. There may be other problems that also block our ability to operate the Compressed File From A Multi-volume Archive (part 4) file. Below is a list of possible problems.

  • Corruption of a 004 file which is being opened
  • Incorrect links to the 004 file in registry entries.
  • Accidental deletion of the description of the 004 from the Windows registry
  • Incomplete installation of an application that supports the 004 format
  • The 004 file which is being opened is infected with an undesirable malware.
  • The computer does not have enough hardware resources to cope with the opening of the 004 file.
  • Drivers of equipment used by the computer to open a 004 file are out of date.

If you are sure that all of these reasons do not exist in your case (or have already been eliminated), the 004 file should operate with your programs without any problem. If the problem with the 004 file has not been solved, it may be due to the fact that in this case there is also another rare problem with the 004 file. In this case, the only you can do is to ask for assistance of a professional staff.

How to associate the file with an installed software?

If you want to associate a file with a new program (e.g. my-file.004) you have two ways to do it. The first and the easiest one is to right-click on the selected 004 file. From the drop-down menu select "Choose default program", then click "Browse" and find the desired program. The whole operation must be confirmed by clicking OK. The second and more difficult to do is associate the 004 file extension to the corresponding software in the Windows Registry.

Is there one way to open unknown files?

Many files contain only simple text data. It is possible that while opening unknown files (e.g. 004) with a simple text editor like Windows Notepad will allow us to see some of the data encoded in the file. This method allows you to preview the contents of many files, but probably not in such a structure as a program dedicated to support them.
