golang open Downloads folder explorer window on Windows 10 not working-CodePudding

I can open a explorer window using on Windows 10 cmd

explorer C:\Users\bruce\Downloads\

So I'm thinking executing this command in go, but it opens Documents folder instead of Downloads folder, how can I solve this issue

package main

import (
    "fmt"
    "os"
    "os/exec"
    "runtime"
)

func main() {
    homeDir, _ := os.UserHomeDir()

    if runtime.GOOS == "darwin" {
        downloadDir := homeDir   "/Downloads/"
        cmd := `open "`   downloadDir   `"`
        exec.Command("/bin/bash", "-c", cmd).Output()
    } else {
        downloadDir := homeDir   "\\Downloads\\"
        cmd := `explorer `   downloadDir
        fmt.Println("cmd: ", cmd)
        exec.Command("cmd", "/C", cmd).Output()
    }
}

Problem solved, turns out that the first parameter of exec.Command() should use explorer instead of cmd

The snippet below is working

package main

import (
    "os"
    "os/exec"
    "runtime"
    "strings"
)

func main() {
    homeDir, _ := os.UserHomeDir()
    downloadDir := homeDir   "/Downloads/"
    if runtime.GOOS == "darwin" {
        cmd := `open "`   downloadDir   `"`
        exec.Command("/bin/bash", "-c", cmd).Start()
    } else {
        downloadDir = strings.ReplaceAll(downloadDir, "/", "\\")
        exec.Command("explorer", downloadDir).Start()
    }
}

Edit

More simplified version, use downloadDir := filepath.Join(homeDir, "Downloads") instead of downloadDir = strings.ReplaceAll(downloadDir, "/", "\\")

package main

import (
    "os"
    "os/exec"
    "path/filepath"
    "runtime"
)

func main() {
    homeDir, _ := os.UserHomeDir()
    downloadDir := filepath.Join(homeDir, "Downloads")
    if runtime.GOOS == "darwin" {
        exec.Command("open", downloadDir).Start()
    } else {
        exec.Command("explorer", downloadDir).Start()
    }
}

Edit2

package main

import (
    "os"
    "os/exec"
    "path/filepath"
    "runtime"
)

func main() {
    homeDir, _ := os.UserHomeDir()
    downloadDir := filepath.Join(homeDir, "Downloads")
    cmd := "open"
    if runtime.GOOS == "windows" {
        cmd = "explorer"
    }
    exec.Command(cmd, downloadDir).Start()
}

[for window]
I recommend using a specific folder instead of joining the path by yourself, because when you install the application on a custom download path, your application will be run with the wrong condition.

a specific folder is a standard folder that was registered with the system and this one is on XP or higher version of window

for manual, you can use like this

win r -> shell:{specific folder}

example

win r -> shell:downloads

for golang you can use like this

err := exec.Command("explorer", "shell:downloads").Start()
if err != nil {
    log.Fatalln(err.Error())
}
