Secondary thumbnail cache

Sorry for creating a thread for such a simple question.

"Added option for a secondary thumbnail cache. When enabled, this will create an additional cache for thumbnails that functions as a backup for the standard cache from Windows Explorer. This will significantly speed up re-generation of thumbnails when items are removed from the standard cache. That may happen frequently when you have a large number of multimedia files, since the standard cache has a limited size."

Where exactly is this option?
Thanks.

Select "Advanced" install mode when doing a fresh install, or uncheck "perform quick upgrade" when doing an update.

Then you can find the option on the "Additional Tasks and Options" page in the installer.

So if i do a quick upgrade this won't be enabled, correct?

Correct, doing a quick upgrade will keep your current settings.

Thanks a lot.
