What feature allows you to search non-indexed areas in File Explorer?

The feature that allows you to search non-indexed areas in File Explorer is disabling index searches. When you disable indexing for a particular folder or drive, it requires File Explorer to perform a full search instead of relying on an index, which only covers indexed locations. This means that when you conduct a search in File Explorer without indexing, it will actively look through the contents of all files, including those in non-indexed areas, leading to more comprehensive search results.

In contrast, viewing hidden files pertains to the visibility of files and folders rather than enhancing search capabilities. Expanding folders helps to navigate through directory structures but does not impact search functionality. Customizing quick access is related to organizing frequently used folders and files for easier access rather than altering how searches are performed in File Explorer. Disabling index searches is specifically focused on broadening the search scope to include all areas of the filesystem.
