The third file of a split archive created with WinZip, a popular file compression utility; uses the same compression as a standard .ZIP file, but is part of a collection of files that make up a single archive.

More Information

Because the Z03 file is the third part of a split archive, it must be decompressed along with a .Z01 and .Z02 file. There may also be a .Z04 file and additional files that make up the split archive.
