After several unsuccessful attempts at getting rid of the file. I found a completely successful way. I made a new user and gave it admin rights. Then I put the stubborn file in a common folder. Next, I logged on as the new admin user, and put the stubborn file in the trash.
Finally, I logged out and back in as the main user. Then I deleted the new user I created. The system then asked if I wanted to delete all files. And just like that, it was gone. This did what all these AppleScripts and apps couldn't seem to do.
robg adds: Over the years, this has probably been one of the more popular topics to discuss -- it seems there are many possible solutions. Even Apple has jumped into the discussion with their You can't empty the Trash or move a file to the Trash in Mac OS X Knowledge Base document. Suffice it to say, there should be something amongst these tips that works for your specific situation.
And yes, if you've been reading here for a while, the above editor's note was cribbed from an earlier deleting files hint (plus I added a few more links that have cropped up since the original was published).]
