This is macOS, not Windows...
copy a file to another location or drive - drag the file to new location while holding the Alt/Option key.
(If you are moving to another folder on the same drive, then the Option key is not needed, just drag and drop the file.
If you want to MOVE a file, so you only have one file, not a copy, even to another drive, again drag to the new location, while holding the
Command key.
It's not the same as Window's cut and paste, but is just how macOS does the job.
