如何在Golang中为exec.command添加空格

Question

How do I use exec.command to start a file with spaces? Adding quotes doesn't seem to work, neither does " or %20 instead of the spaces.

package main

import (
"fmt"
"os/exec"
)

func main() {
    StartProcess("C:\\File With Spaces.txt")
}

func StartProcess(Filename string) {
    Filename = "\"" + Filename + "\""
    cmd := exec.Command("cmd","/C start",Filename)
    err := cmd.Start()
    if err!=nil{
    fmt.Println(err)
    }
}

This works, but only in windows

cmd := exec.Command("rundll32.exe", "url.dll,FileProtocolHandler", Filename)
