Strange files in every directory named "." and ".." in osx 10.9.2 -

-

anywhere ls -a folder contains files called "." , "..".

anybody knows stuff? system files? kind of virus or something? have hard time googling because of such file names.

here example:

drwx------+ 12 mih staff 408 4 янв 16:49 . drwxr-xr-x+ 91 mih staff 3094 20 мар 15:28 .. -rw-r--r--@ 1 mih staff 6148 4 янв 16:49 .ds_store -rw-r--r-- 1 mih staff 0 10 ноя 2011 .localized -rw-r--r--@ 1 mih staff 181 27 ноя 2011 desktop.ini -rw-r--r--@ 1 mih staff 8198298 29 июл 2013 dizzee rascal - bassline junkie.mp3

yes, system files.

a subdirectiry contains 2 directory entries used navigate between folders in days of dos.

the . entry directory reference same directory.

the .. entry directory reference parent directory.

those regular subdirectories, instead point directories exist.

nowadays wouldn't needed, system interpret . , .. anyway, in days needed system find way parent directory.
