Frankly, there isn't a lot to say about AutoDoubler 2.0 except for the fact that it's easier to configure, noticeably faster on my SE/30, and includes the extremely cool CopyDoubler extension for speeding up Finder copies. One interesting note about problems with excluding files did pop up.
Dave Heller, coauthor of AutoDoubler writes, "AutoDoubler 2.0 keeps all of its exclusions and specific settings for each individual volume in an invisible file at the root of the volume. The name of this file is ~AutoDoublerSettings(2.0). It's possible one of these files is corrupt. We keep this separate file so the settings for a disk "travel" with the disk, not the current preferences file in the System Folder. Because this file is invisible, we added a way to reset (delete) this file from within the AutoDoubler control panel. I don't believe the procedure made it into the manual (in all honesty I forgot it was there :-)). Deleting this file will delete all exclusions and settings for the affected disk but it sounds like you may need it. To do so, select each disk listed in the AutoDoubler control panel in turn and click the "Settings..." button while holding down the option and command keys. A dialog box will appear asking if you want to revert the disk's settings to the factory default. Click OK. After doing this to all disks, close the AutoDoubler control panel and reboot. Try adding your exclusions again."
