WinZip makes it easy to create a split Zip file (.zip or .zipx), that is, a Zip file consisting of multiple files of a specified size. There are several reasons why you might want to do this, such as:
- Overcome e-mail size limits: Some e-mail systems limit the size of attachments; if you want to e-mail a large Zip file that exceeds your limit, you can split it into smaller parts and e-mail them separately
- An alternative to spanned Zip files:
- Use this alternative when you want to make multiple copies of the disk set
- Use this alternative when you want to make the disk contents as a separate step from making the disks themselves.
- To assist with large downloads: Some users may have difficulty downloading very large Zip files from web sites, FTP sites, etc. You can use the split Zip feature to break large files into smaller pieces that can be downloaded separately.
