How to Configure WinZip Courier

WinZip Courier is an application for sharing files that is automatically active when you open Microsoft Outlook. It can also integrate with your web browser so that you can zip, protect, and share email attachments directly from (Hotmail), Yahoo! Mail, Gmail, and Zoho. Additional information about usage and configuration with webmail services can be found here.

By zipping email attachments and/or by uploading them to a cloud service and sending a download link, the size of Outlook data files can be kept to a minimum. WinZip Courier can be used with the same Cloud Services available in WinZip. Also, with WinZip Courier conversion features, you can convert Microsoft Office documents to PDF files, you can further protect appropriate image attachments by adding a watermark to them, and/or you can physically resize image files to create much smaller Zip files.

If you are using Courier as part of a WinZip Enterprise license, the services that are available to users is completely within the control of the software administrator and email attachment security can be maintained through the use of encryption and password policies.

Configuring Options in a Message

In each active email message have many configuration options. You can always turn a feature on or off in a message and/or configure how that feature is going to work. By default, Courier will zip the files you attach. If you attach just one file, referred to as single files, they will be zipped if not listed in the exclusions (archive files and some others that will not compress well). Additionally, if the Zip file that Courier builds is 5 MB or larger in size, you will be asked to select a cloud service to which you will then have to login. Courier will upload the Zip file to your selected cloud service and insert a link to the Zip file for the receiver to download the Zip file.

Courier features in a message

The picture above shows the WinZip Courier section of the Message tab in an active Outlook email message. Please note the vertical line that separates three features on the left side from five features on the right side of this section.

The five features on the right side of the WinZip Courier section all affect the options that otherwise run automatically. The Zip Attachments button is highlighted (or "lit up") showing that this feature is turned on. You have the option to:

  • Choose Encrypt (with Zipping) or choose Don't Zip
  • Change the Use Cloud Services settings
  • Choose to use one or more of the options that will convert appropriate file types as they are zipped

By default, all conversions are off. If you would like to change your compression setting (.zip or .zipx) and/or change any of the conversion settings, you can click the Courier tab in your message to do so. Any changes you configure while you are in a message will only affect that message. They will not configure Courier to use those settings by default.

The three features on the left side of the WinZip Courier section are:

  • Attach Large Files: This feature tells Courier to put a placeholder (or placeholders) in the message, in order to bypass Outlook's usual file attachment sequence. It is useful for when there is an attachment size limit enforced by Microsoft Exchange, as it will allow you to send the large file or files.
  • Email from Cloud: This is a sharing feature to use with files you have uploaded to a cloud service already. When you click this button, the Select Files to Share dialog opens displaying all of the available cloud services. You can quickly browse any of the services you have already configured or you can click one, log in to it, and then find the file you want to share. Courier will place a link to your selected file(s) in your email message. No zipping is involved with this feature.
  • Attach file (Zipped): This is a manual zipping feature. When you click this button, you can then select the files that you want to zip and attach, Courier zips the selected files into a single Zip file, and attaches the Zip file to the email message. This feature has two automatic naming options as well as an option for you to type your own name for the Zip file. It also allows you to use either .Zip compression or .Zipx compression.

Exclude Attachments

Attachments Options dialog

WinZip Courier 7.0 introduces the Exclude Attachments feature. This feature in the Attachments Options dialog allows you to specify files that WinZip Courier will never zip (does not apply if Encrypt is selected). In the box provided, you would type an extension for the kind of file that you do not want Courier to ever zip. For example, it may be that you commonly send a number of small text files and do not want these zipped, even if you send more than one. If you want to specify multiple file extensions, place a semicolon between the entries.
