How to delete a folder with space in the name(Golang)

The following codes works in windows:

//suppose I have a fname folder in c:\temp
mydir := "C:\\temp\\dname"
cmd, e := exec.Command("cmd", "/C", " rmdir /S /Q", mydir).Output()

But it will failed if there are spaces in the folder name, like:

mydir := "C:\\temp\\name with space"

The Golang os.RemoveAll can handle the folder name with spaces, but it will fail in the following situation:

C:\> mkdir myprj
C:\> cd myprj
C:\myprj> git init
//add some file
C:\myprj> git add .
C:\myprj> git commit -m "Add my files"
//
//This won't work
err := os.RemoveAll("C:/myprj")

Any ideas on how to remove a folder completely in windows using Go?

Update 1

Either \\ or /is the same error:

func main() {
    if e := os.RemoveAll("c:\\temp\\myprj"); e != nil {
	    fmt.Println(e)
	}
}
//OUTPUT
remove c:\temp\myprj\.git\objectsb8ef36e172ae05842a9326fc73f1c8baa3254: Access is denied.

But I can delete the folder with this command:

C:\> rmdir /S /Q c:\temp\myprj
// or from windows file explore without any problem

I did the same thing on my windows and got the same error too. But I noticed the myprj folder is readonly (in properties) so I turned it off then the code works.

Actually every folder I created on c:\ is "readonly" by default.

And this is not apply to an empty folder the properties says "Read-Only (Only applies to files in folder)".

I found this method works well:

1. Create a batch file myrmdir.bat:

    @echo off
    RMDIR /S /Q %1

2. Place this file in the same folder as the code and call it with:

    //Yes, I can use / instead of \\ and it works
    myfolder := "c:/temp/folder with space" 
    exec.Command("cmd", "/C", "myrmdir.bat", myfolder).Run()

Hope this helps you. If you have a better solution(esp. pure Golang solution) please let me know.
