So, that would be my guess as to why ISO isn't supported. CUE files are necessary for properly accessing Audio CD tracks, and CUE is used in association with BIN as brothered pairs. When inserted into the PC, the PC can detect the data track as data, but won't recognize the audio tracks portion in File Explorer.Īs for why ISO is not used for Audio CD, it just isn't. It has one Track for audio tracks and a Track for the data. Any Audio CD that has data on in when you insert it into a PC is actually a Mixed Mode disc. It can play them, but it can't read 'data' off of them with proprietary software like Windows Media Player or any other CD ripper. So, while they're read on stand alone CD players because they were created for them, Windows had to adapt to read Audio CD's.

So, PC's had to retro fit support for them. It's a proprietary format created long before PC's became popular. Technically, an Audio CD has no 'data' as typically defined by Windows. The 0 bytes being detected for an Audio CD by File Explorer is normal.
