The index closely related to the search feature in Windows Exlporer. With indexed locations, we can search any files or folders in those locations faster than non-indexed locations (read the previous article about "Windows 7 Search Index"). But sometimes in indexed location, the index cannot find files or folders that we looking for, although we are sure the files exist in that location. Over the time, the locations we have used have a lot of changes, such as copying and moving some files in it. So the index would change. In this case, we have to manually rebuild the index to get more accurate results (or we can call it to update the index).
