You can find the size of each folder via the Explorer and Property, but it is beyond control and takes too long. With the windows pc program isimSoftwareFolderSize you get an overview and a tool to review your usage of disk space.
Try it - it's free.
isimSoftwareFolderSize is a simple freeware utility that scans an entire hard disk and provides size-related information for each folder and its subfolders. This will allow you to quickly identify which folders take up the most hard disk space. After the disk scan, the program will provide you with the number of bytes, files and folders that currently occupy a given folder (and its subfolders). You then have the opportunity to immediately delete a given folder (and move it it to the recycle bin).
isimSoftwareFolderSize is an extremely compact tool. Since it's totally portable, too, it can be saved anywhere and run on demand. We clicked the program file and specified our C:/ drive on a small pop-up. The scan took a minute or two, about the same amount of time as comparable tools. When it finished scanning our drive, pop-up appeared, this time bearing a tree view of our C:/ drive. We selected a directory, and a right-hand panel opened on our interface with Space, Files, and Folders data for the directory with and without subdirectories. We could open or delete folders from the interface as well as choose another drive to scan. Navigating through the tree view was easy. Free DiskSpaceExplorer has no Help file or settings, nor are any needed.
isimSoftwareFolderSize is easy to use, and it gave accurate information about Your drives, folders, and files. Since it's totally portable and totally minuscule, too, it's a great addition to portable software toolkits, thumbdrives, and other devices.
