You can delete any files without permission in your /home/user/ folder and in /tmp/ folder you can delete some files that aren't owned by root, other than that, big NO.

You cannot delete files that you don't own from /tmp. Only root has that privilege. Why? Because the folder /tmp has the restricted deletion flag set. ls -dl /tmp gives drwxrwxrwt 12 root root 4096 Jan 3 18:05 /tmp The t in drwxrwxrwxt shows this. –  Paddy Landau Jan 3 '13 at 18:10

To delete a file ,permissions on files have no importance.To delete a file you should have proper permission (write permission) on directory that is housing it.
