WinZip® makes it easy to create Zip files that "span" multiple disks. This is useful if the files you want to compress will not fit on one disk.
To make a Zip file that spans multiple disks, just create a Zip file on a removable disk, and add files and folders to the Zip file as you normally would. If the disk fills during the operation, WinZip will prompt you to insert another disk. Simply insert the next disk and click the OK button.
Example: to zip the files in your C:\DATA folder to a Zip file called A:\DATA.ZIP:
Important: disk spanning is available only when creating a new Zip file, not when adding files to an existing Zip file. You cannot add files to or remove files from a Zip file that spans disks. WinZip requires pre-formatted disks (you can format disks using My Computer or Windows Explorer).
