Zipping a file creates a compressed version of the file that is considerably smaller than the original file. The zipped version of the file has a .zip file extension.1

Reasons to Zip

• You save storage space. Zipping large files can save up to 80 percent or more in hard disk space.
• Smaller file size drastically reduces e-mail transmission time.
• The smaller file size of e-mail messages that you want to keep is useful when your mailbox has a space limit.
• You can send and receive e-mail attachments, such as .exe files, that would otherwise be blocked by an email program or a spam filter for security reasons.
