Since Dropped.on.Caprica's comment is, seemingly, being ignored, I'm escalating it to an "answer" (although I'm wondering whether it should be a new question). The tag cleanup that was requested and moderator-approved here was
... migrate copy to file-copying ...
But the is no file-copying tag on Super User. Questions tagged copy (that refer to copying files) are being coerced into file-transfer. This is not necessarily relevant to questions about local file copying (e.g., Recursive, Non-Overwriting File Copy) or copy protection (e.g., Prevent users from copying files in a directory).
Why aren't we doing this tag cleanup the way it was approved? Why don't we have a file-copying tag?
