Convert 7Z.013 to 002

Understanding 7z.013 and 002 file formats

7z.013 is a part of a split archive created by the 7-Zip compression tool. When large files are compressed and split into multiple volumes, each part is given a sequential extension such as .7z.001, .7z.002, ..., .7z.013. These files are not standalone archives; they are segments of a single compressed archive and require all parts to be present for extraction.

002 files are also split archive parts, commonly used by various archiving tools like 7-Zip, WinRAR, or HJSplit. The .002 extension typically indicates the second part of a split archive, with .001 being the first. Like .7z.013, .002 files are not independent and cannot be converted directly from or to .7z.013 without reconstructing the entire archive.

Can you convert 7z.013 to 002?

Direct conversion from 7z.013 to 002 is not possible because both are parts of different split archive schemes. Instead, you need to extract the complete archive (using all parts, starting from .7z.001) and, if needed, re-split or re-compress the extracted data into a new split archive with the .001, .002, etc., naming convention.

How to extract and re-split archives

1. Ensure you have all parts of the original 7z split archive (from .7z.001 to .7z.013).
2. Use 7-Zip (free and open-source) to extract the archive:
   • Right-click on the .7z.001 file.
   • Select 7-Zip → Extract Here or 7-Zip → Extract to <folder>.
3. After extraction, if you want to create a new split archive with .001, .002, etc. extensions:
   • Select the extracted files/folder.
   • Right-click and choose 7-Zip → Add to archive....
   • In the Split to volumes, bytes field, enter the desired size (e.g., 100M for 100 MB parts).
   • Set the archive format to 7z or zip as needed.
   • Click OK to create new split files (.001, .002, etc.).

Summary

There is no direct conversion between 7z.013 and 002 files. Both are parts of split archives and require all segments for extraction. Use 7-Zip to extract the full archive and, if needed, re-split the data into a new archive with the desired naming convention.
