Description
The CompressLevel property indicates the amount of compression to be performed. The lower the compression, the faster compression takes place. Likewise, stronger compression takes longer but yields the smallest file size.

Valid values are None (CompressionLevelType.None), Low (CompressionLevelType.Low), Medium (CompressionLevelType.Medium), High (CompressionLevelType.High), Maximum (CompressionLevelType.Maximum)

Compressing attachments allows you to save bandwidth, reduce overall file size, and combine several files into a single file.

If you set CompressionLevel equal to "None", no compression will take place but attachments will be combined into a single zip file.

Default Value
If the CompressionLevel is not specified, it will default to Medium.

Usage
See Listing A for an example of the CompressionLevel property in the Auto DB control tag.

Note: Uploaded files (and auto response email attachments) will only be compressed or added to a zip file if you set CompressUploadedFiles="True"
