Why Use Split Archives?

Split archives are useful for several reasons. For example, you can use them to:

• Reduce the size of large files and make them easier to upload, download, or share online.
• Fit large files onto multiple disks or CDs when you have limited storage space.
• Create smaller email attachments that can bypass file size limits or spam filters.
• Protect your files with passwords and encryption when you store or send them.
