.7z.020 — 7-Zip Split Archive Part 20
Igor Pavlov · 2000s
This is the 20th part of a larger archive file split into multiple volumes by the 7-Zip compression software.
Key Features
- Part of a multi-volume archive.
- Created by the 7-Zip compression tool.
- Sequential numbering indicates order.
- Requires all parts for full extraction.
Best For
- Storing and transferring extremely large files.
- Achieving high compression ratios.
- Creating archives that can be easily managed in parts.
- Distributing large files to users with limited download bandwidth.
Less Ideal For
- Storing single, small files.
- Quickly accessing individual files without extracting the entire archive.
- Sharing files where compatibility with basic unzipping tools is essential.
- When encryption is not a primary concern (though 7z supports it).
Common Use Cases
- Splitting very large files or folders for easier sharing via email or cloud storage.
- Archiving extensive datasets that must fit onto specific media like DVDs or USB drives.
- Distributing large software packages or game installations in manageable chunks.
- Backing up large amounts of data in a segmented manner.
How to Open It
- Ensure you have all sequential parts (.7z.001, .7z.002, ..., .7z.020, etc.) in the same folder.
- Install 7-Zip (Windows) or a compatible unarchiver like Keka (macOS) or p7zip (Linux).
- Open the first part of the archive (e.g., the .7z.001 file) with your chosen program.
- Select the files you wish to extract and choose a destination folder.
What is a .7z.020 file?
The .7z.020 file extension signifies the 20th part of a multi-volume archive created using the 7-Zip compression utility. 7-Zip is a popular open-source file archiver known for its high compression ratios, especially with its native .7z format. When a large file or collection of files exceeds the desired size limit for a single archive, 7-Zip can split it into multiple smaller parts, sequentially numbered. This allows for easier transfer, storage on smaller media, or managing large datasets.

Common Problems with .7z.020 Files
Frequently Asked Questions
Yes, all sequential parts must be present in the same directory to successfully extract the original files.
You should open the first file in the sequence, which usually has the lowest number (e.g., .7z.001).
No, individual parts cannot be opened on their own. They are segments of a single, larger archive.
Technical Details
These files are not standalone archives but rather sequential segments of a larger .7z archive. Each part contains a portion of the compressed data. To access the contents, all parts of the archive must be present in the same directory, and the first part (typically .7z.001) needs to be opened with a compatible decompression utility.
