This article explains how to turn off the index(Link). I'm not interested in turning off the index, but I'm curious about 2 different options.
In "Turn Off Indexing Selectively" section from the article, they turn it off by modifying Indexing Options. In "Turn Off Indexing for a Drive" section, they turn off Allow files on this drive to have contents indexed in addition to file properties. I wonder if those settings behave differently.
For example, If I added a path "C:\Foo" from Indexing Options but turned off Allow files on this drive to have contents indexed in addition to file properties from the folder properties, is the folder indexed? If so, what is Allow files on this drive to have contents indexed in addition to file properties for?
