By default, you can search for files from the Start Menu of Windows 10. However, the Start Menu’s search is very broad – it searches both the Internet and the entire contents of your computer. By using the File Explorer’s Search tab, you can create more powerful and specific searches.
To launch File Explorer, hit the WINDOWS+E key from either the Desktop or the Start Screen. When File Explorer launches, click on the small magnifying glass icon to the right of the Search box. This will bring up the Search Tools tab on File Explorer’s Ribbon. The Search Tools themselves have three categories – Location, Refine, and Options.
Location will let you set the specific folder or folders than the search will use. This is useful if you are looking for a particular file within a specific set of folders, but do not want to search the entire computer.
The Refine tools allow you to adjust the parameters of the search. You can adjust by Date Modified, Kind (the type of file you are searching for), the size of the file, the file’s name, metadata, or extension. This can come in handy if you are looking for, say, a misplaced Word document, and do not want the search to find other types of files that have similar names.
Finally, Options allows you to review and reuse recent searches, save searches (if you find yourself performing the same set of searches over you can save it), and to open the location of a file found in the search.
