The problem with floppies (most of the time) is that they have to be used in floppy drives. So many issues arise with floppies because of head alignment differences between drives. Which is why so many people abandoned those floppies at the first chance they had (ZIP drives anyone?).
It is easier to go back to the machine with the data that was stored on the floppy and take/lend/give an USB memory stick or (USB) CD/DVD burner or USB harddisk to put the data on one of those mediums. My suggestion assumes that the data is on the original system and then copied to floppy.
If that is not the case...
Accessing the floppy on a different computer in your care is not possible? Or maybe go even lower by accessing the floppy directly without using Windows and its ways to access the floppy. Likely there is software there for this purpose. In the days when the Commodore 64 was king I had such a piece of software. When I was in that 'scene'
it was always a nice boost for your ego when you see a disk from a stranger...with your personal ascii art embedded into its file listing.
So, if the humble C64 was able to do that, than there has to be software for 'those damn IBM clones' as well
