如何使用exec.command启动带有空格的文件？添加引号似乎无效，“或％20代替空格也不起作用。

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)
    }
}
