Z01 is the first of multiple files that together create a larger file archive created with WinZip tool. The file stores data that when combined with volumes create a complete ZIP archive.
Z01 files use the same archivization standard as ZIP files. Spliting a large archive into smaller volumes makes sharing files on the internet easier and allows to overcome size limitations if such are imposed. Splitting is typically used for very large file archives.
Z01 extension is used for the first volume of the split archive. Each subsequent volume is given suitable extension name, i.e. Z02, Z03 etc. Process of unpacking the archive can be completed only if all the split volume files are present in the same folder – the program will automatically recreate the original archive from archive parts.
