I never really questioned it, but now, after a year, I do. After a reinstall of OSX, I have some strange folders in my /-directory. I'll list it here with the first three files or folders in the directory. I would leave it alone for the while being, but all in total takes up some space and it annoys me. Could I safely delete all things or make it hidden by placing a dot before each folder, without any errors? Thanks for reading.
