Configuring WinZip Courier: Attachments Options

The Attachments Options window controls how the Zip file attachment is named as well as several aspects of the zipping process. There are two versions of this dialog; however making changes in either dialog will affect all of WinZip® Courier. The screenshots and options listed are from Courier 7; if you have an older version, you may not have all of the listed options.

One way to access this dialog is through the WinZip Options in Outlook. The Attachments dialog will look like this:

Alternatively, you can access the Attachment Options dialog through the Configure WinZip Courier application on the Start menu. This Attachments Options dialog will look like this:

Zip file name

Zip files before attaching to message

This controls whether the default in WinZip Courier is to automatically zip all attachments or not. When this checkbox is checked, the Zip Attachments button on the new email message ribbon or toolbar is selected by default; all email attachments in Outlook are automatically zipped before sending unless you manually click on the Zip Attachments button to deselect it. When this checkbox is unchecked, the Zip Attachments button on the Outlook ribbon or toolbar is not selected by default and you will need to manually click on it to select it before WinZip Courier will zip your attachments.

Default Zip file name

This is the default Zip file name, used when WinZip Courier automatically zips multiple attachments. To change the name, simply type a new name in the space provided. Do not include drive or folder names.

Use custom file extension

Zip files normally use the ".zip" or ".zipx" extension. Some e-mail systems may restrict or reject attachments with this extension due to security concerns.

If you find this to be a problem, you can instruct WinZip Courier to use a different extension for your zipped attachments; simply type the extension you want to use in the Use custom file extension field and check the box in front of the field. For example, if you type "zea" (zipped e-mail attachment), the zipped attachments might be named "WinZip Courier Compressed Attachments.zea" rather than "WinZip Courier Compressed Attachments.zip".

  • Of course, if you use this feature you must be especially careful about the contents of your attachments. Be certain that all of your attachments are checked and safe.
  • This option also affects WinZip Courier's Send as Zip File feature in Word, Excel, and PowerPoint. Documents that you zip and e-mail from your Office applications will also use the alternate extension.
  • This option also affects WinZip Courier's feature for manual zipping e-mail attachments. Files zipped using this feature will also use the alternate extension.

You will need to let your recipients know that the attachments are Zip files. In general, your recipients will not be able to open the zipped attachments by double-clicking them as they normally would (but see below). Recipients will need to use the "Save As" feature in Outlook to save the attachment with the normal ".zip" extension.

Recipients to whom you frequently send Zip files with an alternate extension may be able to configure Windows to "know" that these are Zip files so that they can be opened normally.

For example, a recipient using WinZip and Windows Vista or later could follow these steps:

  1. Right-click the WinZip desktop shortcut and choose "Run as administrator".
  2. Choose the Settings tab and click Options (or pull down the Options menu and choose Configuration).
  3. In the System tab of the Configuration dialog, check the box to "Associate WinZip with the specified alternate extension for Zip files".
  4. Enter the alternate extension you want to use in the "Alternate Extension" field.
  5. Click OK to close the configuration dialog and save your changes.

The alternate extension is now associated with WinZip and the attachments can be opened by double-clicking.

For other versions of Windows or other Zip file utilities, consult your system and program documentation.

Compression method

In the Compression method section, you can choose the compression method to be used in automatic zipping. Choose Zip: Legacy (compatibility) or Zipx: Best method (smallest size), depending on what Zip file utilities your recipients have; please read about compression methods for further information.

Single attachments

Zip file name

This area changes the default Zip file name for messages with only one attachment and which single attachments get zipped.

  • If you check Use single attachment name instead of the default Zip file name, WinZip Courier will use the base name of the attachment, with the extension changed. For example, a file named "2006 Sales.doc" would be zipped as "2006 Sales.zip".
  • If you uncheck Use single attachment name instead of the default Zip file name, WinZip Courier will use the default name as specified in the Default Zip file name field.
  • If you check Allow conversion of a single attachment without zipping, when you attach only a single file and then choose any of the conversion options such as, Resize Images, Convert to PDF, or Watermark Images, WinZip Courier will not zip the single attachment after converting it.
  • Don't zip single attachments smaller than controls the minimum size of a single attachment that WinZip Courier will zip. By default, WinZip Courier zips all single attachments, regardless of size, except those that are excluded due to file type (see below). If you would prefer not to zip small, single attachments, you can adjust this value. For example, if you would prefer not to zip attachments that are less than 5000 KB (approximately 5 MB) in size, set this value to "5000".
  • If a message has multiple attachments, all of the attachments will be zipped; attachment size is not considered.

  • The Don't zip single attachments with the following file extensions allows you to specify the types of files that WinZip Courier will not zip. WinZip Courier will not normally zip single attached compressed archives, including attached Zip files. You can edit this list to add or remove file name extensions. Separate the extensions using semicolons; it is not necessary to include the dot before the extension. Note that Zip files are always excluded.
  • The Reset extension list to default setting button resets the list of excluded extensions to its original (default) value.

Remember that

  • these exclusions apply only to single attachments (multiple attachments are always zipped), and that
  • they are ignored if encryption is requested.

Exclude Attachments

Entering a file extension into the Never zip attachments with the following file extensions field will always exclude those particular files from being zipped--EVEN when you have attached multiple files. For example, if you never want your VCF files to be zipped, enter vcf into this field.
