please add an option to display 0 B in size column for folders with 0 byte size...i have a folder with 3 subfolders and they're all 0 byte(i didn't know since i think they're all created by the system) and when I turned on calculate folder size..nothing was displayed..I thought it was a bug but then I realized that they have 0 byte size..if only 0 was displayed there'll be no confusion..so please..just an option..
