Windows
Explorer in Vista makes it very easy for you to manage large folders
that have hundreds of files and sub-folders (e.g. Program Files or the
Windows installation folder).

Earlier, if you were to hunt for files that end with a .log
extension or are larger than 2 MB, Windows search was the only option
but things get much simple in Vista Explorer.

Just navigate to the relevant folder in Windows Explorer, click the drop-down next to the name tab and choose "Stack by Name".

This will immediately group the files by name and it will become relatively easy for you to reach the relevant files.

You can apply similar search filters to group files by size or by file type (extension).

Internally, this is also using the built-in desktop search of
Windows Vista but the implement is more user-friendly and very
efficient.
