the hidden files start with a . like
.raynon
.asdf
.dfhg

these are hidden files.If you want to see this you have to put
ls -al

it will show u all the files including the hidden files.
But the first two lines that is
./
../

they shows the link to current directory and the parent directory respectively.when we create a directory these two links are created automatically.

total 16 means the directory is taking 16 blocks of memory.
