WinZip® makes it easy to create Zip files that "span" multiple disks. This is useful if the files you are working with will not fit on one disk.
To make a Zip file that spans multiple disks, simply create a new Zip file on a removable disk, then add files to the Zip as you normally would. If the disk fills during Add operation, you will be prompted for another disk. Simply insert the next disk and click the OK button.
Important: disk spanning is not available when adding files to an existing archive; it is only available while creating a new archive. Also note that 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).
Example:
To zip the files in your c:\data folder to a Zip file called A:\DATA.ZIP:
If more than one disk is needed, you will be prompted for additional disks.
To extract files from a spanned Zip file, insert the last disk of the series and open the Zip file using WinZip; this will display the directory of the Zip file and allow you to extract the files. WinZip will prompt you for the disks as needed to complete the operation.
