Suppose so. They took a complete disc, sector by sector, and wrote it as a file.

That's kinda what I expected actually... so you reckon they're just in
normal raw image format for e.g. Rawrite?
Recently found some long-lost images of 5
1/4" floppies that were sent
to me... 10-15 years ago. Here's one of them:
http://www.corestore.org/RP06.552
Seems to be a MSDOS 5.0 boot disk, with just one important program,
RP06.EXE, on it, and then some support programs.
As far as I can see, it is a physical backup. Could the 552 just be a serial
number `?

I would agree that it is just a sector by sector binary dump done with
something like dd or rawwrite, however it is not a 5.25 diskette the
format is 80 trks 18 sect 2 heads and media descriptor is 0xF0 which
would be a 1.44 MB 3.5 diskette.
