Note for registered users
Before you install version 4.0, we’d like to make sure you know that you’ll be asked to pay a $14.95 upgrade fee if you purchased Default Folder X before June 1, 2007. We don’t want anyone to feel that they weren’t told about this before trying the new version. Thanks for your continued support!
