Convert A00 to A04

Understanding a00 and a04 file formats

A00 and A04 files are both parts of a multi-volume archive created by the ARJ compression utility. When a large file or set of files is compressed and split into several parts using ARJ, the first part is typically named with the .arj extension, and subsequent parts are named sequentially as .a00, .a01, .a02, and so on, up to .a04 and beyond. These files are not standalone archives; they are segments of a single compressed archive and must be combined to extract the original data.

How to convert a00 to a04 files

Since .a00 and .a04 are not different formats but rather sequential parts of the same ARJ archive, conversion between them is not applicable. Instead, you need to extract the contents of the entire multi-part archive. This process involves using an archive manager that supports ARJ multi-volume archives.

Best software for handling a00 to a04 files

The most reliable software for extracting ARJ multi-part archives is WinRAR or 7-Zip. Both support ARJ files and can handle multi-volume archives seamlessly.

• WinRAR: Open the folder containing all parts (.arj, .a00, .a01, ..., .a04), right-click the .arj file, and select Extract Here or Extract to [folder].
• 7-Zip: Right-click the .arj file, choose 7-Zip → Extract Here or Extract to "[folder]".

Ensure all parts are in the same directory before extraction. The software will automatically use the .a00 through .a04 files as needed.

Summary

There is no direct conversion between .a00 and .a04 files, as they are segments of a single ARJ archive. Use WinRAR or 7-Zip to extract the complete archive by starting with the .arj file and ensuring all parts are present in the same folder.
