In Ubuntu (14.04) in the nautilus window (the file explorer) I can right-click on a folder and select Properties to see its size. However, this size does not include hidden files. (dotfiles) Is there any way to get a folder's real size?
For example, it says
3 items, totalling 4.2 kB when, in fact, I am sure there are hundreds of gibibytes in this folder in dotfiles. The question is, how many hundreds?
To clarify, my question is specifically about including hidden files in the total size. So, how much disk space does the folder take up? Not reformatting the same number.
