Hello

I'm working on a project with Eclipse and by now everything was fine, but last time I've tried building it, it returned the error

"The project was not built due to "Could not delete '/Torpedo/bin/bin'.". Fix the problem, then try refreshing this project and building it since it may be inconsistent Torpedo Unknown Java Problem"

and it deleted my bin folder which stores all the images and stuff needed for the program. (Fortunately I had a backup). I've tried googling it and tried every solution I found, but nothing helped, and also most of them suggests to delete the folder by hand, which I can't. What should I do? Thanks.
