I have system partition on my Windows 10 PC. It contains files

EFI
--Microsoft
----Boot
------bootmgr.efi
------bootmgfw.efi
------bootmgr.efi
------...other files
----Recovery
--Boot
----boot64.efi
--Dell

My C: drive also contains EFI folder

c:\windows\Boot\EFI\
------bootmgfw.efi
------bootmgr.efi

I select bootmgr.efi file when do boot order settings in BIOS.

But what all other *.efi files is used for? Why I have separate partition for EFI? Why my c:\Windows\boot folder also contains EFI?

Does this answer your question? Why does Windows 10 use a separate 100MB partition for UEFI since with UEFI it can read in the filesystem in C:\Windows\System32\winload.efi?

That’s the original location of the files, from where they are copied to the actual boot partition.
