Z01 files are split ZIP archive files, commonly created by WinZIP or compatible tools. If you’re encountering challenges opening a Z01 file or are simply interested in its contents, we’re here to clarify the properties of these files and recommend software capable of handling Z01 files.

What is a Z01 file?

A .Z01 file serves as part 1 of a Split ZIP Archive. These files are generated by compression tools like WinZIP, which compress collections of files into a single archive file. The primary purposes of such archives are to save hard drive space and facilitate the distribution of file collections.
As archive files can become quite large, there’s a need to split them into smaller parts for storage on CDs or USB drives. When an archive is split, each part receives a numbered file suffix. Files with the Z01 extension represent part 1 of the split ZIP archive, while the last part is given the ZIP extension.
To access the content within a .Z01 file, it’s essential to have all the archive part files in the same folder. Open the last file (with the ZIP extension) using your compression tool. Some tools may also allow you to extract the archive by selecting the Z01 file, but it’s advisable to consistently open the .ZIP file to ensure compatibility.
