Convert PIZ to R73

Understanding the PIZ and R73 file formats

PIZ files are typically compressed archives, most commonly associated with renamed ZIP files. Sometimes, email clients or malware disguise ZIP files as PIZ to bypass security filters. These files can be extracted using standard archive tools after renaming the extension to ZIP.

R73 files are part of a multi-volume RAR archive set, specifically the 73rd part of a split archive. RAR archives are widely used for compressing and splitting large files into smaller, manageable parts for easier distribution or storage.

How to convert PIZ to R73

Direct conversion from PIZ to R73 is not a standard process, as these formats serve different purposes. However, you can extract the contents of a PIZ file and then re-compress them into a multi-part RAR archive, which will generate R73 files if the archive is large enough.

Step-by-step conversion process

1. Rename the PIZ file: Change the file extension from .piz to .zip.
2. Extract the ZIP archive: Use an archive tool like 7-Zip or WinRAR to extract the contents.
3. Re-compress as multi-part RAR: Open WinRAR, select the extracted files, and choose Add to archive....
4. In the archive options, set the Archive format to RAR and specify a volume size (e.g., 100MB) to split the archive into parts.
5. Click OK to create the multi-part RAR archive. If the archive is large enough, WinRAR will generate files named .part1.rar, .part2.rar, ..., and eventually .r73, .r74, etc.

Best software for the conversion

• 7-Zip – Free and open-source tool for extracting ZIP/PIZ files.
• WinRAR – Industry-standard tool for creating and managing RAR multi-part archives, including R73 files.

Summary

While there is no direct PIZ to R73 converter, you can extract a PIZ (ZIP) archive and repackage its contents into a multi-part RAR archive using WinRAR. This process will generate R73 files as part of the split archive set if the total size requires that many parts.
