What is a .z01 file?
File Extension Details
The Z01 file extension represents the first segment of a split or multi-volume compressed ZIP archive. When a user needs to compress a very large file or folder structure that exceeds storage limits, email attachment sizes, or file system constraints, compression software like WinZip or 7-Zip can split the resulting archive into smaller, more manageable pieces. The first split volume is assigned the .z01 extension, the second .z02, and so on, while the final file in the sequence retains the standard .zip extension. To successfully extract the contents of a split archive, all numbered parts (including the .z01 file) must reside in the same directory, and the extraction process must be initiated by opening the primary .zip file. If any part of the sequence is missing or corrupted, the entire archive cannot be decompressed.
