Gnome-DO: Difference between "Locate files" and "Files and folders" plugins?

"The locate files plug-in uses the locate command to search for files on your entire computer. You use it by typing ""locate"" into gnome-do and pressing tab, then entering your search term, pressing enter and scrolling through the results. I've used it in the past but I have a terminal open all the time anyhow so turned it off.

Files and Folders, by default, indexes all the files and folders in your /home/username, /home/username/Documents, and /home/username/Desktop but can be configured to index whichever folders you like. It can be a handy way to pull up a folder or a file you reference often.

I use Files and Folders and configured it to index a few other folders I commonly use."
