Come and thank me after downloading! Can't the attachment be larger? A file of over 7M needs to be split into 29 parts. It's not easy to upload and downloading is troublesome.

First, don't get off and say thank you first! It's obvious it's not easy.

The content discussed is based on 360K floppy disks, and I've never seen such old relics. I don't know if there's any reference value for the current 1.44M floppy disks. Let's take a look first.

Not bad! Just read the first more than twenty pages, and it feels valuable for reference. Isn't the 1.44M one a modified version where the number of tracks per side is doubled, the number of sectors per track is doubled, and the capacity is exactly increased by four times?
