The Z01 file type is a zipped or compressed file; it is part of a group of files known as a spanned zip file. Spanning is used to break larger files into small pieces for saving on a disk or emailing. The Z01 file will have at least one other file in the group; each file in the group will end in Z01, Z02, Z03 and so on until the entire span is completed. There is a trial utility that is easy to use that will open Z0X files.
