What is a Z01 file?
A Z01 file is the first of multiple files that make up a split archive created with Corel WinZip, a popular file compression utility for Windows. It contains one or more files that have been compressed with Zip compression to save space.
Z01 split archives are often used to shrink the size of large files for e-mail attachments or file downloads. They can only be decompressed if the related split archives (.Z02, .Z03, etc.) are available.
