You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: watcher.go
    path of file: ./repos/watcher
    
    the code of the file until where you have to start completion: package watcher

import (
	"errors"
	"fmt"
	"io/ioutil"
	"os"
	"p
    
func (w *Watcher) Remove(name string) (err error) {
	w.mu.Lock()
	defer w.mu.Unlock()

	name, err = filepath.Abs(name)
	if err != nil {
		return err
	}

	// Remove the name from w's names list.
	delete(w.names, name)

	// If name is a single file, remove it and return.
	info, found := w.files[name]
	if !found {
		return nil // Doesn't exist, just return.
	}
	if !info.IsDir() {
		delete(w.files, name)
		return nil
	}

	// Delete the actual directory from w.files
	delete(w.files, name)

	// If it's a directory, delete all of it's contents from w.files.
	for path := range w.files {
		if filepath.Dir(path) == name {
			delete(w.files, path)
		}
	}
	return nil
}
