|Support for spanning to diskettes is no longer available. If you are using an older WinZip version and would like information on spanning to diskettes, please see Zip file spanning with diskettes. A WinZip Pro license is required in order to span Zip files to CD and DVD.
If a Zip file will not fit on a single disc, WinZip Pro will create a Zip file that spans multiple discs automatically. To burn a new Zip file to a CD/DVD device use New Zip file on CD/DVD on the Application menu in the WinZip ribbon interface (on the File menu with Legacy menus/toolbar). It is also possible to burn a new Zip file to a CD or DVD when using the Job Wizard.
Supported disc formats are: CD-R, CD-RW, DVD-R, DVD+R, DVD-RW, and DVD+RW (spanning is not supported with Blu-Ray discs).
Note: The maximum amount of data written to a DVD from WinZip is 4gb.
If WinZip is configured to use the Legacy menus/toolbar interface, an existing Zip file can be written to CD/DVD. To do this, choose the Send ToCD or DVD option on the File menu. However, you must make sure your Zip file will fit on one disc in this case as spanning only works when creating a new Zip file.
Unzip a spanned Zip file
To unzip a spanned Zip file, first insert the last disc of the spanned series and open the Zip file using WinZip; this will display the list of files and folders and allow you to extract them. WinZip will prompt you for each disc as needed to complete the operation.
