Download Directory Size Monitor 2.5

Directory Size Monitor Explorer Extension adds a new column to the Details view in Windows Explorer. The new column shows not only the size of files, but also the size of folders.
It gives you the chance to keep track of which folders you view, and scans them in the background so you can see complete size of all files within the folder. It's very useful for cleaning up your disk. Once you get used to having that information available, a directory listing simply looks incomplete without it!
Key Features
· Background folder scanning.
· Folders are scanned in a recursive round-robin order, fairly updating viewed folders.
· The last requested folder is always scanned before any previously requested folders.
· When "drilling down" into your folders, the scanner will narrow its search tree as you enter each subfolder.
