I'm learning this more and more, it's a problem sometimes.

Agreed...

I noticed that there also seems to be a hidden file for each visible
file. A PITA when copying photos/files from an Apple product. Is there
a way to copy JUST the file and not the hidden file(s)?

Yes!!! Back a bit, I was copying photos from multiple sources, into one
large collection. I had 'duplicate names' and I guess I let some to be
overwritten - then I discovered some pix I knew I had were missing! I
finally figured it out, but not before losing some older pix I really
wanted to keep. I now have some work-arounds for that...
