Using Android and Win11, and details of how copy works in win11 may be
different from win10, or at least important: 

There's probably a better way to do it but I copy my photos from my
phone to my PC (and later to a backup drive) by displaying the phone's
camera folder in MyPhoneExplorer's file manager, highlighting the ones
that are newer than the ones in the PC, and dragging them to the folder
in the PC. 

Today I found a cache of photos in a 3rd location on the phone.  I
understand why external and internal storage, but why two locations in
internal storage?  So to help myself to look further later, I created a
new folder in the PC and copied everything to it.  About 626 files, took
80 minutes, no problem, I'm not going anywhere. 

But at the end, it found 6 files that already existed in the destination
folder.  How can that be when it was a new folder?  I said to keep both
and give a new name to the ones copied in.  When I look, after the copy
completed, I have 6 pairs of files, and the date, time, and size are the
same for each pair. They really are the same.   Did it get mixed up and
start copying a second time?  Then why did it stop after 6? 

Complicating this a bit is that I first started to copy the files to the
correct folder, realized that the new files would be lost among the old
files and stopped the copy after less than a minute, time enough maybe
to copy in 6 files and indeed those same 6 files are in the already
existing destination folder.  Can something about being copied the first
time cause them to be copied to the new folder too?  How can that be?
The new folder didn't exist when I mistakenly copied a few files to a
different existing folder. And the new folder could not have been a
duplicate of the existing folder because it was new and I copied nothing
into it other than that one big copy. 

In Win11, when it says there are duplicate files in source and
destination, does it say that when it finds them or at the end of the
whole process?  Either way, this is no easier to solve.  It did know
there were 6 of them when it brought up the message box.
