Files transferred but queue continues

I transferred many files to my website 2 weeks ago, but whenever I go into FTP I see half these files still in a queue. How do I delete them?
WS_ftp was a lot better product with simple drag and drop action - Is it still available?

I have spent 35 minutes deleting the 250 items in the queue one at a time then started the queue manually on the item I want. Surely there must be a quicker way, or, am I using the wrong product for transferring files to server and back?

Select all the items in the queue and press the DEL key. You can also use Ctrl+A to select all the files.
