Please don't refer to commands like DIR or RM as DOS commands. The ones you want to use are Windows terminal/console commands. If you really wanted to use DOS RM command, you'd have to use ntvdm.exe, Windows NT Virtual DOS Machine

I got the same error as you.
But dystroy is correct: You can't run del or any other command built into cmd because there is no del.exe file (or any other del-executable for that matter).

I got it to work with:

package main



import(

    "fmt"

    "os/exec"

)



func main(){    

    c := exec.Command("cmd", "/C", "del", "D:\a.txt")



    if err := c.Run(); err != nil { 

        fmt.Println("Error: ", err)

    }   

}

You need a Windows cmd to execute your dir command.
