.7z.002 — 7-Zip Split Archive Part 2
Igor Pavlov · 2000
This is the second segment of a larger archive file that has been split into multiple parts by 7-Zip for easier handling or transfer.
Key Features
- Part of a multi-volume 7-Zip archive.
- Used to break down very large archives.
- Requires all parts to be present for extraction.
- Utilizes 7-Zip's robust compression.
Best For
- Splitting extremely large archives that exceed storage or transfer limits.
- Organizing large datasets for easier distribution.
- Creating backups that can be stored on multiple physical media.
Less Ideal For
- Single, small archives that do not need splitting.
- Creating self-extracting archives (use .exe variants).
- Sharing individual files that are not part of a larger archive set.
- When a single compressed file is preferred for simplicity.
Common Use Cases
- Splitting large software downloads into multiple files.
- Distributing large media collections across several parts.
- Archiving extensive project files for backup or transfer.
- Sending large data sets via email or file-sharing services.
How to Open It
- Ensure all parts of the split archive (.7z.001, .7z.002, etc.) are in the same folder.
- Install 7-Zip (Windows) or a compatible alternative like Keka (macOS) or p7zip (Linux).
- Right-click on the first file (.7z.001) and select 'Extract Here' or 'Extract to [Folder Name]'.
- The program will automatically find and use subsequent parts (.7z.002, etc.) to reconstruct the original archive.
What is a .7z.002 file?
The .7z.002 file extension signifies the second part of a multi-volume archive created using the 7-Zip compression utility. When a large file or a collection of files is compressed into a single 7-Zip archive, it can be split into smaller, more manageable parts. These parts are typically named sequentially, starting with .7z.001, .7z.002, and so on. To access the contents, all parts of the archive must be present and then opened with a compatible 7-Zip program.

Common Problems with .7z.002 Files
Frequently Asked Questions
Yes, you need all sequentially numbered parts of the archive to successfully extract the original files.
No, you can only open the first part (e.g., .7z.001), and the software will automatically use the subsequent parts like .7z.002.
.7z is a single, complete archive file, while .7z.002 is a part of a larger archive that has been split into multiple volumes.
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, with the primary archive information residing in the first part (.7z.001). The 7-Zip format itself uses the LZMA or LZMA2 compression algorithm, offering high compression ratios.
