I have an older Win 7 PC that I have networked via ethernet to my newer Win 10 PC, to facilitate transferring files between the 2.
However, when I'm on my Win 10 PC, I can only COPY files from the Win 7 PC, and I want to be able to MOVE or DELETE them, so when I'm finished, my Win 7 PC is "cleaned." But, if I try to do anything other than copy... I get a message about "needing permission," even though I have enabled all sharing permissions (Read, Write, Delete, etc) for the entire hard drive on the Win 7 PC. What am I doing wrong?

I really don't want to have to keep switching my keyboard, mouse, and monitor between the 2 in order to do "housekeeping."
Why can't I control everything from the Win 10 PC?
Any help would be GREATLY appreciated.
