What is the Preview Cache for?

When you select a photo in the browser panel, the time it takes for the photo to load is dependent on quality of the preview rendered. PhotoDirector lets you render a preview of each photo (which is saved in the preview cache location folder) to enable faster load times when browsing through them.
Location: the location on your computer where the preview data is saved.
Note: You may manage your cache size in Preference window to limit the maximum size.
