I am working on a project but I need to delete over a hundred costumes in a single sprite. I don't want to do it manually, so is there any way to do this?

you could move the code to a different sprite and the costumes you want.

You can copy a costume over to another sprite by dragging the costume on top of the sprite, like this:

You could also find a way to remove the images on your computer.

thx for the help people! I really appreciate it.
