Ashampoo Burning Studio uses .ashdisc files to represent disk images created from actual physical media (DVD/CD). It is a not well-known format, so many often wonder how to open, convert or burn .ashdisc files, because they never heard about the program.
Except for the obvious Ashampoo Burning Studio, some other disk image management / burning utilities such as PowerISO, or gBurner supposedly support this format and can convert it to any of the supported alternatives, including CD/DVD binary image (.bin), which essentially represents ashdisc to bin conversion.
