Can the same USB Pendrive contain MULTIPLE BIOS files?

I take this to the extreme level. I have a single USB Flash Disk that has all of this on it:

1) All my BIOS versions for all my machines.
2) Every current Windows 10 ISO from Microsoft (all bootable from that UFD)
3) Every current Windows 11 ISO from Microsoft (all bootable from that UFD)
4) Modified Windows ISO images including Sysprepped editions and editions with drivers injected (again, all bootable)
5) A collection of unattended answer files selectable by menu
6) A separate partition that has all my important docs, software, media, etc. BitLocker encrypted
7) Another partition not BitLocker encrypted so that I can place files on it to be shared with others.
8) All drivers for every machine
9) More

The point is simply this: Not only can you put all your BIOS files on the same UFD, you can do WAY, WAY, WAY more all on a single UFD.

Hope you don't lose it then!

As SIW2 already mentioned, If you use the BIOS eazyflash all you need is the BIOS file.
And I recommend that you only update BIOS using BIOS eazyflash/
May I ask why don't you create multiple folders each one named with the BIOS version? You just need to browse to the folder you want and load the corresponding file.
