Folder size is a light patch that adds a small column of Windows Explorer that shows the size of the file in a window.
When we use Windows Explorer, it shows the column in the folder and file, type, date of correction and file size (not the size of the folder).
Thanks to the folder size, we will see how a new column will appear in our window and we will show the total size of the files in that folder.
This is a very useful patch that can save us some time and which can be useful if we have to delete any of our folders for more free space on the HD. Note
After we install the patch, we have to enable it. How active? See -> Choose Detail -> Folder Size
