I have just found a cd, in a drawer, that I cannot identify & cannot remember whether it is something I have copied, downloaded, or been given. When opened it contains many files which are not titled, simply numbered & with .mbd file extension. Windows will not open them nor will any other program on my pc, but I am loathe to throw it away. Is there a generic programme that will open files with this extension or would I have to have the programme that created the files in order to open them?Thanks
