...e main part of the question then is: "Why to use it and is it necessary at all?". The only reason to prefer the syntax of "./file" instead of "file" I was able to find is that ./ means current folder and ONLY the current folder. So if there is some kind of tool/compiler/etc that searches for the fil...
