Convert R10 to 7-Z

Understanding r10 and 7-z file formats

R10 files are part of a multi-volume archive created by WinRAR. When a large file is split into several parts for easier distribution or storage, each part is given a sequential extension such as .r00, .r01, ..., .r10, and so on. These files cannot be used independently; they must be combined with the other parts to extract the original content.

7-Z files are compressed archives created by 7-Zip, a popular open-source file archiver. The .7z format offers high compression ratios and supports strong AES-256 encryption, making it a preferred choice for efficient and secure file storage.

How to convert r10 to 7-z

Direct conversion from a single .r10 file to a .7z file is not possible, as the .r10 file is only a segment of a complete archive. To convert, you must first reconstruct the original file by extracting the entire multi-part RAR archive, then compress the extracted content into a .7z file.

Step-by-step conversion process

1. Ensure you have all parts of the RAR archive (e.g., .rar, .r00, .r01, ..., .r10).
2. Use WinRAR or 7-Zip to extract the complete archive:
   • With WinRAR: Right-click the .rar or .r00 file → Extract Here
   • With 7-Zip: Right-click the .rar or .r00 file → 7-Zip → Extract Here
3. After extraction, you will have the original file or folder.
4. To create a .7z archive:
   • Right-click the extracted file/folder → 7-Zip → Add to archive...
   • In the dialog, set Archive format to 7z and click OK.

Best software for the job

• 7-Zip (Windows, free, open-source): Handles both RAR extraction and 7z compression.
• WinRAR (Windows, trialware): Required if you encounter extraction issues with 7-Zip.

Summary

To convert an r10 file to 7-z, you must first extract the entire RAR archive using all its parts, then recompress the extracted content into a .7z file using 7-Zip. This ensures data integrity and optimal compression.
