Convert 7Z.020 to 001

Understanding 7z.020 and 001 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.

001 files are also split archive parts, commonly used by various archiving tools. The .001 extension typically denotes the first part of a split archive, with subsequent parts named .002, .003, and so on. Like .7z.020, a .001 file is not a complete archive by itself.

Can you convert 7z.020 to 001?

Directly converting a .7z.020 file to a .001 file is not practical or meaningful, as both are parts of split archives but from potentially different archiving schemes. Instead, to access the contents, you need to recombine and extract the entire archive using the correct tool. If you want to create a .001 split archive from a 7z set, you must first extract the files and then re-archive them using a tool that supports .001 splitting.

How to extract and recombine 7z split archives

To access the contents of a .7z.020 file, you need all parts of the split archive (from .7z.001 up to .7z.020). The extraction process will automatically recombine the parts.

Best software for handling 7z split archives

• 7-Zip (Windows, free): The native tool for 7z archives. Download from 7-zip.org.
• PeaZip (Windows/Linux, free): Another excellent archiver supporting 7z and split files.
• Keka (macOS, free): A popular choice for Mac users.

Step-by-step: Extracting a 7z.020 split archive

1. Ensure you have all parts of the archive (.7z.001, .7z.002, ..., .7z.020) in the same folder.
2. Right-click on the .7z.001 file.
3. Select 7-Zip → Extract Here or Extract to [folder].
4. 7-Zip will automatically process all parts and extract the complete content.

How to create a .001 split archive from extracted files

1. After extracting the original archive, select the files you want to split.
2. Right-click and choose 7-Zip → Add to archive....
3. In the Split to volumes, bytes field, enter the desired size (e.g., 100M for 100 MB parts).
4. Set the archive format to zip or 7z as needed.
5. Click OK. The resulting files will be named .001, .002, etc.

Summary

While you cannot directly convert a .7z.020 file to a .001 file, you can extract the contents from the split 7z archive and then re-archive them as a .001 split archive using tools like 7-Zip. Always ensure you have all parts of the split archive before attempting extraction or conversion.
