|The Attach Large Files feature in WinZip Courier applies to Microsoft Outlook users and requires a ZipSend account
Starting with WinZip Courier 3.5, the Attach Large File feature is available. You may need to use this feature if:
- Your email is governed by an Exchange Server or other similar email server and an attachment size limit is in use
- Your attachment(s) will be near or over the imposed size limit
Files close to the size limit may be a problem
What follows is a short explanation of what Outlook and WinZip Courier are doing when files are attached and automatic zipping is enabled. This will point out how the issue occurs.
- When attaching files to an Outlook email message, copies of those files are placed into Outlook's SecureTemp folder
- When the Send button is clicked, Courier creates a subfolder in the Temp folder
- Courier places its own copies of the attached files into the subfolder it has created
- The files are zipped and the Zip file is moved into Outlook's SecureTemp folder
- After the Zip file is successfully moved and the attachment list updated, the original file attachments are deleted
By waiting to delete the original attachment(s), Courier is insuring that they will not be lost if, for instance, there is some sort of outside interference. However, if the attached files are close to the limit enforced by the mail server, the Zip file size added to the size of the original files will usually be more than the limit allows and an issue occurs.
Using Attach Large Files and why it eliminates the issue
If you know you will be sending files that will be close to the size limit or will total to a larger size than the limit, you can avoid an issue by using the Attach Large File button. To do this:
- Open a new message in Outlook and fill in the appropriate information
- When you are ready to attach files, click the Attach Large File button
- Find and select your files and click Attach
- Courier will put small placeholder attachments in your message
- When all is ready, click Send, Courier will Zip your files, and the Zip file will be uploaded to your ZipSend account
Note: ZipSend progress will display in the lower left corner of your main Outlook window
- The recipient of your message will receive a link to your Zip file that can then be downloaded
This will avoid the attachment size limit, because only the very small placeholder files will be created in the Outlook SecureTemp folder. The final Zip file will be uploaded to your ZipSend account directly from the subfolder Courier creates in your Temp folder.
