I’ve never met a GREAT copywriter who uses a swipe file…
At least, not the way you see them taught so often.
As in, copy-paste-edit.
Sure, some may SELL YOU a swipe file on the promise that you can write great copy that way — even as they themselves don’t follow this process to write anything important.
(There’s some ethical questions there I’ll suggest and let you wrestle with.)
But when it comes to actually writing copy that matters…
They don’t “swipe” the way you think of it.
And most really good copywriters I know don’t even have a swipe file, or whatever they once collected is now collecting dust.
