Here’s a quick but useful trick courtesy Tom Kuhlmann.
Windows Explorer, by default, will sort your list of folders by name so a lesser-used folder like “archives” will have a more visible position than, say, the “important” folder.
However, if you would like to keep your frequently-used file folders “pinned” near the top of the Explorer pane, you can easily do that by adding a symbol (like ~, !, ^ but not | or *) to the name of the folder.
Other than symbols, digits may also be used but I think a nomenclature like “~important” sounds slightly better than “1important” or “1-important” though the prefix doesn’t matter as far as Windows Search is concerned.
