Notes about the ISOD file extension:
Incorrect file associations could be the result of underlying issues within your PC system. As such it is highly recommended to scan your PC for invalid registry entries, unused processes and other unfavourable system settings to identify slowdown issues.
The ISOD file type is primarily associated with 'CloneDVD' by Elaborate Bytes AG. Rename the file and it should be recognized as a standard ISO file by different programs.
