The File System ImgBurn is using is "ISO9660 + UDF". So if it is using UDF why isn't it preserving the spaces? Here is what I did:
Burn disc of data (which consists of various games), load newly created disc, explore disc and see that all filenames and directories with spaces have been converted to conform with ISO9660. I changed nothing in how I make discs, the only thing that changed is I upgraded ImgBurn. What I need to know is what default seting can I set so that I don't have a problem with this again?
