Where are crontab files stored in OS 10.8 I've already looked at this question:

Where is my crontab file?

But there is no real answer except for 10.7.  I'm trying to migrate crontab from an old drive that I can't boot so using crontab -e is out of the question.  Just need to read the user crontab file to pull existing jobs to a new server.
My current version is 10.8 after check : 

  /var/at/tabs


and name of file is value of logged => $user .

For my comp : 

  /var/at/tabs/nikola


Don't change permission use vim or nano ...
