Convert 7Z.026 to 003

Understanding 7z.026 and 003 file formats

7z.026 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.026. These files are not standalone archives; they are segments of a single compressed archive and require all parts to be present for extraction.

003 files are also commonly associated with split archives, typically created by file splitting tools like HJSplit or similar utilities. The .003 extension indicates the third part of a split file set (e.g., .001, .002, .003, etc.). Like 7z split files, .003 files are not usable on their own and must be joined with the other parts to reconstruct the original file.

Can you convert 7z.026 to 003?

Direct conversion between 7z.026 and 003 is not meaningful because both are parts of different split archive systems. Instead, if you need to change a 7z split archive into a generic split file set (like .001, .002, .003), you must first extract the complete archive and then re-split the resulting file using a file splitter.

How to extract and re-split your files

1. Gather all parts of your 7z split archive (from .7z.001 to .7z.026) in the same folder.
2. Use 7-Zip (free, Windows/Linux) to extract the archive:
   • Right-click the .7z.001 file and select 7-Zip → Extract Here.
   • 7-Zip will automatically use all parts to reconstruct the original file.
3. Once extraction is complete, use a file splitter like HJSplit (free, Windows) to split the extracted file into .001, .002, .003, etc. parts:
   • Open HJSplit and select Split.
   • Choose the extracted file and set the desired part size.
   • Start the split process. The output will include a .003 file as the third part.

Recommended software for the process

• 7-Zip – Best for extracting .7z split archives. Free and open-source. (Download 7-Zip)
• HJSplit – Simple tool for splitting files into .001, .002, .003, etc. (Download HJSplit)

Summary

There is no direct conversion from 7z.026 to 003 as both are split archive parts from different systems. To achieve a .003 file from a 7z split archive, extract the full archive with 7-Zip and then split the resulting file with HJSplit or a similar tool.
