Zip files contain one or more files.
Zip files make it easy to group files and make transporting and copying these files faster. These files provide most of the benefits of Zip files, but use different file formats. WinZip can handle Zip, TAR, gzip, and CAB files by itself. External programs are required for the less frequently used ARJ, ARC, and LZH formats. Zip files save time and space, and make downloading software and transferring e-mail attachments faster.
