The z01 file extension is associated with WinZIP. Its one part of a multi-volume compressed ZIP archive.

ZIP file extension is used for the native format of WinZip archiver. In WinZIP you can split a huge archive to a few smaller files, which are called parts.

WinZip uses this split file sequence for multi-volume archives:

  • zip or exe (SFX) for first volume
  • z01, z02, z03 ....etc. for any additional volumes

WinZip, the original and most popular compression utility for Windows, is a powerful and easy-to-use tool that quickly zips and unzips your files to conserve disk space and greatly reduce e-mail transmission time.

In order to unpack the multi-volume ZIP archive, you need to place ALL of the split parts in the same directory and start extraction of the first volume. The program will automatically use all of the parts to extract the content of the archive.
