How to create a split Zip file

The ability to create a Zip file (.zip or .zipx) consisting of multiple files of a user-specified size is a feature supported by the current version of WinZip, which is available for download at the WinZip web site.

To access the Split feature, please do the following from a WinZip Classic window:

1. Open My Computer or Computer (in Windows Vista and Windows 7)
2. Highlight (select) the files and/or folders you would like to zip
3. Right click one of the selected objects and the context menu will appear with several WinZip Add features; Select Add to Zip file
4. If necessary, name the Zip file
5. Set the Split Zip file drop down menu to the size of the segments you would like to split the Zip file into. You can specify your own size by choosing Other size in the drop down list and type the desired size in the "Other size" field. You can select bytes, KB (kilobytes), and MB (megabytes) for the unit of measurement.
6. Click Add to create the Split Zip file.

Depending on the number of segments, the result is a sequence of files named filename.zip, filename.z01, filename.z02, and so on. The naming convention for split Zipx files is filename.zipx, filename.zx01, and so on.

We recommend that the recipient of these files use the current version of WinZip to open and extract the contents of the split file, although WinZip 9.0 or later can be used.

If you have an existing Zip file that you would like to split, open the Zip file in WinZip Classic mode, and then choose Split from the Actions menu.

1. Specify the name to be used for the Split Zip file. The name must be different from the name of the open Zip file.
2. Specify the size to be used for the individual parts. You can choose from common sizes using the Part size drop-down list or you can specify your own size. To specify your own size, choose Other size in the drop down list and type the desired size in the Other size field.
3. Click OK to create the Split Zip file.

Note: The Split icon is not placed on the toolbar by default; however, you can modify which buttons appear on your toolbar.

1. Start WinZip by double-clicking the WinZip shortcut on the desktop
2. Choose Configuration from the Options menu
3. Click the Toolbar tab
4. Click on Select Buttons
5. Add or remove buttons from your toolbar to suit your needs
