Opening Z01 files

Have a problem opening a .Z01 file? We collect information about file formats and can explain what Z01 files are. Additionally we recommend software suitable for opening or converting such files.

What is the .Z01 file type?

The .z01 extension belongs to a series of sequential alphanumerical filename extensions used to identify parts of multipart, or multi-volume (also, split-volume) ZIP archives.

ZIP is a lossless data compression algorithm and archive file format currently supported by the vast majority of archive managers on all platforms. A regular ZIP archive is a single .zip file that contains compressed individual files, directories, or directory structures inside.

Besides regular archives, many ZIP archive managers support creation of multi-volume archives. These are ZIP archives that consist of multiple section files of equal size, arranged in a certain order through specific extensions assigned to them. Such extensions can follow several different patterns, depending on the archiving tool used (e.g., .z01, .z02, .zip.001).

Thus, a .z01 file is the second part of a multi-volume ZIP archive, implying at least the existence of the .z00 file (the first section). For successful extraction of data from a split-volume ZIP archive, all its part files (.z00, .z01, etc.) must be present in the same directory at the time of extraction.
