The first of multiple files that make up a split archive created with WinZip; uses the same compression as a standard .ZIP file, but must be decompressed along with the related split archives (.Z02, .Z03, etc.).

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 all the split archive segments are available.
