The "Web-style" folders view, with the left Explorer pane displaying details for the object currently selected, is turned on by default. For certain file types, such as pictures and media files, a preview is also displayed in the left pane.<ref>{{cite web|url=http://www.microsoft.com/technet/prodtechnol/windows2000serv/reskit/prork/prde_ffs_sleq.mspx?mfr=true|title=Managing Files, Folders, and Search Methods: Microsoft TechNet|website=microsoft.com|access-date=June 19, 2018|archive-date=January 12, 2009|archive-url=https://web.archive.org/web/20090112123850/http://www.microsoft.com/technet/prodtechnol/windows2000serv/reskit/prork/prde_ffs_sleq.mspx?mfr=true|url-status=live}}</ref> The [[Windows 2000]] Explorer featured an interactive media player as the previewer for sound and video files.

[[Shortcut (computing)|File shortcuts]] can also store comments which are displayed as a tooltip when the mouse hovers over the shortcut.

The right-hand pane, which usually just lists files and folders, can also be customized. For example, the contents of the system folders aren't displayed by default, instead showing in the right pane a warning to the user that modifying the contents of the system folders could harm their computer. It's possible to define additional Explorer panes by using [[Div (HTML tag)|DIV]] elements in folder template files.<ref name="ActiveDesktop">{{citation

Search capabilities were added, offering full-text searches of documents, with options to filter by date (including arbitrary ranges like "modified within the last week"), size, and file type. The [[Indexing Service]] has also been integrated into the operating system and the search pane built into Explorer allows searching files indexed by its database.<ref>{{cite web|url=http://msdn.microsoft.com/en-us/library/ms689718.aspx|title=What is Indexing Service?|website=msdn.microsoft.com|date=November 6, 2009 |access-date=June 19, 2018|archive-date=January 1, 2011|archive-url=https://web.archive.org/web/20110101192618/http://msdn.microsoft.com/en-us/library/ms689718.aspx|url-status=live}}</ref> The ability to customize the standard buttons was also added.
