another question, is there any big difference between these type of image files.. such as a matter of space or quality?
About PC CD-DVD copy protection emulation there're some differences, Alcohol MDF it's probably the most advanced, DMPS burn/emulation for example.

About compatibility, Clone CD IMG are BIN, CDrwin images, and the subchannel data is stored on the .SUB file. The CCD stands for a kind of CUE. Btw, the CUE files created by Clone CD with the compatibility mode are most of times incorrect for multi track CD images. Alcohol MDF are not directly compatible with any format as I said before.

Ok, here's a really quick rundown.

ISO files are a standardized format of file, with a particular sector size. Pretty much any disc that doesn't have some weird-oh physical characteristics or protection can be stored as an ISO. However, there are other reasons to use the other types. For the MOST part, however, ISOs are just fine.

BIN/CUE files are similar to ISOs with a couple key differences. First, the sector size is different. Second, the CUE file is used to keep track of the number of tracks, the track gaps, the track formats, etc. This allows a little more flexibility in the file. For example, Exact Audio Copy rips CD's as one big WAV file... and a CUE file. The CUE file tells the program where to put the track gaps, etc.

IMG files are pretty much like ISO, just a slightly different format.

MDS/MDF files are VERY different. This format can keep track of PHYSICAL characteristics of the disc. This includes subchannel data, physical disc errors (i.e. copy protection), etc.
