Convert Z20 to Z01

Understanding z20 and z01 file formats

Z20 and Z01 files are both parts of a split archive created by the popular compression utility WinZip. When a large file is compressed and split into multiple segments, each segment is given a sequential extension: .z01, .z02, ..., up to .z20, and so on. The process allows for easier storage and transfer of large archives. These files are not standalone archives; they are segments of a single compressed archive, and require all parts (including the main .zip file) to be present for extraction.

Can you convert z20 to z01?

There is no direct conversion between .z20 and .z01 files, as both are simply numbered parts of a split archive. Renaming a .z20 file to .z01 will not make it usable as the first segment, and may corrupt the archive. If you need to recombine or reorder the segments, you must re-create the split archive from the original source files.

How to extract split archives with z20 and z01 files

To access the contents of a split archive, you need all the parts (.z01, .z02, ..., .z20, and the main .zip file) in the same folder. Then, use a compatible extraction tool to open the .zip file. The software will automatically use the other segments in the correct order.

Best software for handling split zip archives

• WinZip – The original tool for creating and extracting split archives. Open the main .zip file and extract as usual.
• 7-Zip – A free and open-source alternative that supports split archives. Right-click the .zip file and select 7-Zip → Extract Here.
• WinRAR – Another popular tool that can handle split zip files. Open the .zip file and use Extract To.

How to create a new split archive

If you need to change the number of segments or their order, re-create the split archive from the original files:

• In WinZip, use File → New Archive, add your files, then select Split and choose the segment size.
• In 7-Zip, right-click your files, select 7-Zip → Add to archive..., then set Split to volumes, bytes.

Summary

There is no direct conversion between .z20 and .z01 files. Both are parts of a split archive and must be used together with the main .zip file for extraction. Use tools like WinZip or 7-Zip to manage and extract these archives.
