More Information

This hotfix will not compress the unusually large images previously created by scanning with Twain. In order to return the files to their proper sizes, you will need to use a file compression application. Once the files have been compressed, you can recalculate the volume's size. See the following Knowledge Base article for more information on recalculating volume size:
