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. 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. 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. If folder size information is updated it means that on every file operation the system must update this information. Why is that? Imagine for a moment how this should work at all and the reasons will be quite clear. While this is true there is a pretty good reason for it.įirst of all none of the files systems support such option by design, which means that it is not available to the operating system.

Recently I came across some posts on forums from people complaining that there is no Folder Size column in Windows 7.
