There are some situations where a file or folder refueses to be deleted by selecting " Empty Trash...". What to do? Since Mac OS X is based on BSD UNIX, we can use the command line to do the "dirty" work.
Open the Terminal
Start by double clicking /Applications/Utilities/Terminal. You are now faced with the UNIX command line.
Empty the Trash
We now need to issue a command to empty the trash. Note: Be very careful to type this exactly, better yet copy and paste it (The $ is the prompt, don't type/copy this). Why you ask? There is a potential to erase large parts of your hard drive. Enough said.
$sudo rm -Rf ~/.Trash/*
