Convert 7Z.003 to 002

Understanding 7z.003 and 002 file formats

7z.003 is a part of a multi-volume archive created by the 7-Zip compression tool. When large files are split into several parts for easier storage or transfer, each segment is given a sequential extension such as .7z.001, .7z.002, .7z.003, and so on. These files are not standalone archives; they are fragments of a single compressed archive.

002 files, in this context, refer to the second part of a split archive, often created by archiving tools like 7-Zip or WinRAR. Like .7z.003, a .002 file is not a complete archive but a segment of a larger, split file set.

Can you convert 7z.003 to 002?

Directly converting a 7z.003 file to a 002 file is not meaningful, as both are sequential parts of a split archive. The numbering (.001, .002, .003, etc.) is determined during the archive creation process. Changing the extension or renaming the file does not alter its content or function. To access the data, you need the complete set of split files and must extract them together.

How to extract split 7z archives

To work with split archives, gather all parts (e.g., .7z.001, .7z.002, .7z.003) in the same folder. Use an extraction tool to combine and extract the contents.

Best software for handling split archives

• 7-Zip (Windows, free): The most reliable tool for creating and extracting split 7z archives.
• WinRAR (Windows, paid with trial): Also supports multi-part archives, including 7z and RAR formats.
• Keka (macOS, free): A popular choice for Mac users to handle split archives.

Steps to extract a split 7z archive using 7-Zip

1. Place all parts (.7z.001, .7z.002, .7z.003, etc.) in the same directory.
2. Right-click the .7z.001 file.
3. Select 7-Zip → Extract Here or 7-Zip → Extract to <folder>.
4. 7-Zip will automatically process all parts in sequence and extract the complete archive.

Summary

There is no practical conversion from 7z.003 to 002 as both are parts of a split archive. Use extraction software like 7-Zip to combine and extract the full contents from all parts.
