Self-organize files in the downloads folder (automatically)

I guess you've probably seen many projects that monitor the downloads folder and organizes the files there into a sub folder matching the file type.
This is one more of them! But you don't have to run it every now and them...it actively monitors the folder as new files are downloaded, so you don't have to do anything ?. It even shows a notification whenever a new file is moved!

package main

import (
    "encoding/json"
    "fmt"
    "io"
    "log"
    "os"
    "path/filepath"
    "time"

    "github.com/fsnotify/fsnotify"
    "github.com/gen2brain/beeep"
)

func alert(title, message string) {
    err := beeep.Alert(title, message, "warn.png")
    if err != nil {
        panic(err)
    }
}

func move(filename, baseFolder, jsonFile string) {
    time.Sleep(2 * time.Second)
    extMap := getExtensionMap(jsonFile)
    folders := getFolderNames(extMap)
    if isFolder(filename, folders) {
        return
    }

    folder := getFolderName(extMap, filepath.Ext(filename))
    createFolder(baseFolder, folder, folders)
    src := fmt.Sprintf("%s/%s", baseFolder, filename)
    dest := fmt.Sprintf("%s/%s/%s", baseFolder, folder, filename)
    os.Rename(src, dest)
    alert(fmt.Sprintf("New file to: %s", folder), fmt.Sprintf("Dest: %s", dest))
}

func startWatching(baseFolder, jsonFile string) {
    watcher, err := fsnotify.NewWatcher()
    if err != nil {
        log.Fatal(err)
    }
    defer watcher.Close()

    go func() {
        for {
            select {
            case event, ok :=
