Although Internet speeds are getting quicker and email providers are offering more mailbox storage space, it's still no excuse for bombarding people with huge attachments. Yes, I know it's much easier to just dump the original file you want to send into the message, but programs like WinZip Companion mean you don't have to do this. The application allows you to zip and unzip files within Outlook with the greatest of ease.

WinZip Companion delivers several useful tools for helping you achieve smaller file sizes. The plug-in, which works exactly like the popular WinZip utility, provides a handy interface for compressing files directly before they are sent. It can bundle several different files into a single attachment, making things a lot easier for both you and the recepient of the email.

It's also very secure, because the software boasts built-in 256-Bit encryption. This means you can apply passwords to attachments so that they can only be opened by those who are authorised to do so. You can also opt to exclude certain file formats from compression if you so desire.

If you're an Outlook user and you send and receive attachments regularly then you can't afford to be without this program, as it will dramatically speed up transfer times and save precious space in your mailbox
