The documentation page for Folder Index https://www.voidtools.com/support/every ... _indexing/ states
But in my experience the last part is not true. If the folder's drive is unplugged the folder index remain unchanged, even when I in settings select it and click "rescan now".What happens if the indexed folder is offline or not available?
The folder index will remain unchanged.
However, forcing a index rebuild will show the folder as empty.
I request a right click menu action in the settings to clear the index for a folder.
