But you could open a terminal window as the file owner, and execute a simple rm on the file itself, right? I don’t know if dragging it to the recycle bin chowns it, though.
If you are comfortable using a command line, that would be the easiest way to remove individual files. Moving files to the Trash does not change the owner, but it does make ordinary files read only.
So open the terminal window application which you will find at:
/Applications/Utilities/Terminal.app
Then in the Terminal window go to the .Trash folder by typing in this command at the prompt (pressing the return key at the end of each command):
cd ~/.Trash
Then get a listing of the files with this command:
ls
Then remove the files one at a time with this command:
rm -f "name of file"Since you don't have write permission on the file in the .Trash folder, using the -f option will force delete it.
