[Closed] Enumeratefiles collect unwanted fileextensions

Hi,

Im trying to use enumeratefiles to collect all used bitmaps in the scene. My main problem is that it picks up files that aren’t supposed to be treated as a bitmap for example .cube (problem with corona scenes).

So my question is, are there any way to see all kind of fileextensions that enumeratefiles “support” or how can I filter away non supported files that cant be opened with openbitmap?
