I am running win 7 on a workstation. The windows indexing function is running properly. If I enter a filename into the windows search box it is found instantly. But when I am in LR CC and I select the option to show the file in Explorer, LR begins a slow search that can take 30 seconds or more, marked by a progress bar across the top of the screen. Is LR not using windows own index tables but doing a tedious search each time?
