You can compress multiple files together to create a single file in your cPanel account. This is also known as "zipping" or "archiving" files.

From your client area go to:

Services -> My Services -> click on the green "Active" button -> Login to cPanel/Control Panel

In the top left-hand corner of the account Dashboard, select File Manager.

In the cPanel File Manager, select the files you want to compress, and then select Compress. Complete the fields, and then select Compress Files.

More info: For more help, see the cPanel documentation for File Manager.
