How to delete swf files?

[Mitzah]

I think he means, he copied .thm files where the .swf ones should be. That's easy...just click on an item you wish to delete, and press delete, situated bottom right.

Ohhhh I'm Sorry it was fault with my eye :D
Yeh you can hilight that .thm file and then press F8 to delete. It easy like Mitzah said :p
