Excellent write-up on the details of the Windows 9x setup distro package FYI 1,802,240 (1.72M) is actually the capacity of an obscure floppy format that Micro$oft created, but it was found that some floppy drives could not read it, so it was abandoned. I have attempted to recreate this format, and my floppy drives can read and format it fine, but other drives may have problems with 84 tracks.
