Given a directory specifier that represents the top of a mounted filesystem (ex: "C:" or "D:" for Windows, "/" for Linux, etc.), is there a fast, high-level way to get an estimate (not necessarily exact or particularly accurate) of the total number of files and/or directories (it doesn't really matter which) contained within it? I know there's always the brute force approach -- recursively parsing the directory tree and physically counting the number of files and directories found along the way, but the whole reason why I'm trying to estimate the number in the first place is so I can provide some kind of meaningful progress estimate while the REAL work -- recursively parsing the directory tree and looking for duplicate files --   More>>
