Method Purge

backend/union/union.go:242–263

Purge all files in the directory Implement this if you have a way of deleting all the files quicker than just running Remove() on the result of List() Return an error if it doesn't exist

(ctx context.Context, dir string)

//
// Return an error if it doesn't exist
func (f *Fs) Purge(ctx context.Context, dir string) error {
	for _, r := range f.upstreams {
		if r.Features().Purge == nil {
			return fs.ErrorCantPurge
		}
	}
	upstreams, err := f.action(ctx, "")
	if err != nil {
		return err
	}
	errs := Errors(make([]error, len(upstreams)))
	multithread(len(upstreams), func(i int) {
		err := upstreams[i].Features().Purge(ctx, dir)
		if errors.Is(err, fs.ErrorDirNotFound) {
			err = nil
		}
		if err != nil {
			errs[i] = fmt.Errorf("%s: %w", upstreams[i].Name(), err)
		}
	})
	return errs.Err()
