Command 1on1 (Delete folder2's files with same name hash of folder1)

This is 1on1, as Julius Erving and Larry Bird Go One on One
My all-time favourite basketball game

We want to deduplicate a folder against another one
It is used to make a folder "lean", eliminating files that have been copy-pasted

dry run =hash,=filename,multithread

zpaqfranz 1on1 c:\dropbox -deleteinto z:\pippero2 -ssd

wet run 0 files too

zpaqfranz 1on1 c:\dropbox -deleteinto z:\pippero2 -zero -kill

Real run, with XXH3, with *

zpaqfranz 1on1 c:\dropbox -deleteinto z:\pippero2 -xxh3 -kill -forcezfs
