Recently I came across some posts on forums from people complaining that there is no Folder Size column in Windows 7. While this is true there is a pretty good reason for it.
First of all none of the files systems support such option by design, which means that it is not available to the operating system. Why is that? Imagine for a moment how this should work at all and the reasons will be quite clear. If folder size information is updated it means that on every file operation the system must update this information. While this may not be a heavy operation if you save or delete a few files just think if you copy or move millions of files? Such operation will take ages. On the other hand you have at least 500 files open in your operating system at any given time (including ones used by the operating system itself) so all those have to be constantly tracked.
Such tracking will lead to immense system slow-down and if it was really implemented the people from those forums that complain about the folder size column not being implemented would be complaining against it. 😉
What do you personally prefer – a constantly slow system because of a feature that you use rarely or just to look for an alternative to scan your folder sizes under Widows 7?
Folder Size is not available not only in Windows 7, but also in Windows 8, Windows XP, Windows Vista, Windows NT, Linux, Mac OS or any other operating system because of the performance issues mentioned above.
I hope I have managed to explain this clear enough. I personally like the thinks they are and I use this FREE Folder Size application whenever I need it. It is very lightweight and fast and has a beautiful interface resembling the one of Windows Explorer with plenty of charts. This is my personal favorite in the disk cleanup process.
