Convert 7Z.020 to 003

Understanding 7z.020 and 003 file formats

7z.020 is a part of a multi-volume archive created by the 7-Zip compression tool. When large files are split into smaller parts for easier storage or transfer, each segment is given a sequential extension such as .7z.001, .7z.002, ..., .7z.020. These files are not standalone archives; they are fragments of a single compressed archive.

003 files are also commonly seen as split archive parts, often created by file splitting tools like HJSplit or similar utilities. The .003 extension typically indicates the third segment in a sequence (e.g., .001, .002, .003).

Can you convert 7z.020 to 003?

Direct conversion between 7z.020 and 003 is not meaningful, as both are simply sequential parts of split archives, not actual file formats with content to convert. Renaming a .7z.020 file to .003 will not make it compatible with splitters like HJSplit, nor will it allow extraction unless all parts of the original archive are present and in the correct order.

How to handle 7z.020 and 003 files

If you have a set of .7z.001, .7z.002, ..., .7z.020 files, you should:

• Ensure all parts are in the same folder.
• Open the .7z.001 file with a compatible archiver.
• The extraction tool will automatically process all subsequent parts, including .7z.020.

For .003 files, you need the complete set (e.g., .001, .002, .003) and a compatible joiner or extractor.

Best software for extracting split archives

• 7-Zip (Windows, free): Right-click the .7z.001 file and select 7-Zip → Extract Here.
• PeaZip (Windows/Linux, free): Open the first part and extract as usual.
• Keka (macOS, free): Drag the first part into Keka to extract.

For .003 files, use HJSplit or 7-Zip if the files are part of a split archive.

Summary

There is no direct conversion between 7z.020 and 003 files. Both are split archive parts and require the full set of files and the appropriate extraction tool. 7-Zip is the recommended software for handling .7z.020 files, while HJSplit or 7-Zip can be used for .003 files if they are part of a split archive.
