Ugh! What an ugly typo! That should be "*three* kinds of .ipd files,"
of course.

Hello,
A long time ago, I read a book, I do not remember whether it was about
MS-DOS or about assembly programming (I think it was MS-DOS), that
presented the basics about a different formatting for a floppy disk,
introduced as a way of some sort of cryptography, so that the floppy can
only be read with the intended software. Easy to imagine a transposition
to a CD, and then a DVD.
You know, space aliens are not the only ones willing to protect their
data. About applying this to the medical context, I guess Micky has an
idea about whom to speak about it with.
The only question in my mind would be, what tool made
CDROM-XA in the first place ? Maybe the hospital diagnostic
instrument was programmed by space aliens ? Space aliens like
to make trivial changes to formats, to confuse the humans.

They are not a match in this case.
I don't know if the OPs file is exactly this format or not,
but you have a look at it with your hex editor, and see if
it matches your filext suggestions. The mypacs site has
sample medical imaging stuff. This series (61840350) had
something to do with someone's knee.

OK, I'll believe you. I was just pointing out what the extension often
referred to.

There are a variety of techniques, but most were security by obscurity
at best, as any number of tools would see through them. Usually the idea
was a bad/fake allocation table, or changing the disk's apparent size,
or similar.
These techniques often relied upon the media being read/write, and could
not be easily translated into write-once media such as CD/DVD.
Regardless, these are simply not encryption techniques. If you want
encrypted storage, use encrypted storage, there are a variety of
options.
