Conversion of fdd files to mem file format

It looks like that both .fdd (floppy disk image) and .mem (memory dump) files are used by Parallels Desktop virtualization software, but it is unlikely one can be converted to another or vice versa because of their different nature. Memory dumps are typically generated when some error is encountered and these files are not created with some kind of conversion, certainly not fdd to mem conversion.
