"eraser" folder

I was wondering why there is a folder inside of the CloneDVD folder called “eraser” and it contains two folders; NTSC & PAL…and then a series of .ifo and .vob files…is this here by mistake…or does it serve a purpose??

Path: C:\Program Files\Elaborate Bytes\CloneDVD2\eraser

They serve a very important purpose. If you modify or delete them, CloneDVD will no longer work correctly.

Thanks Olli, I didn’t know if it was something left over from a test period or not.

Is it okay to delete the language and manual folders?
