When you want to see only the kinds of files that interest you during browsing, and there is a "technical" way to define what you want, use the Filter. Any files that do not meet the conditions you set will be temporarily hidden.
The Filter window lets you set exactly the same kinds of conditions as you can set for the Search function. The conditions are divided into tabs (sections). You can disable an entire tab at once using the checkbox by its name.
Note that filter conditions in checkmarked tabs are used even if those tabs are not currently displayed!
You can filter by full or partial filename, date of creation, date of last changes, size, name, author, description, keywords, technical details like shutter speed, or GPS information.
To turn the filter on and off, use Organize | Filter… or the Filter button on the main Browser toolbar.
