To drill down through a series of ], for example, on a desktop means to move through the hierarchy of folders (from the top downwards) to find a specific file or to click through drop-down menus in a GUI. Clicking on an item moves you to a level of greater detail. When an online user accesses more and more pages of the website, they may delve deeper into the content of the site. As a web-surfer goes further into a website, they go deeper into the back pages and thus deeper into data.

Drilling down through a ] involves accessing information by starting with a general category and moving through the hierarchy: from category to file/table to record to field.
