Windows does not show newly inserted files in a directory of a real android device /sdcard/Download/

Question

I have an Android application that I import an Sqlite file into the application to perform the queries and changes. When finished manipulating I export that same file to a user-accessible folder so I can grab the same file and use it.

ANDROID VERSION: 4.4.4

I have this function to import the file

 public void ImportarDB()
 {
    try
    {
        string script1 = "cp /sdcard/Download/file.db /data/data/br.com.app.inventario/file.db";
        Java.Lang.Runtime.GetRuntime().Exec(script1);
         script1 = "rm /sdcard/Download/file.db";
        Java.Lang.Runtime.GetRuntime().Exec(script1);
    }
    catch (Exception)
    {

    }
 }

And this one to export

 public void ExportarDB()
 {

    try
    {
        string script1 = "cp /data/data/br.com.app.inventario/file.db  /sdcard/Download/file.db";
        Java.Lang.Runtime.GetRuntime().Exec(script1);                                         
    }
    catch (Exception)
    {                   
    }
 }

After executing the function "Exportardb" my directory looks like this:

Already on my Android device consulting by the ADB command line the directory appears like this:

The two images refer to the same directory, I wonder how do I update my directory on Windows as soon as I insert a new file.

Note: It is not feasible to restart the device or the machine. I tried to unplug the usb and plug again; already tried these 2 snippets of code but do not work:

SendBroadcast(new Intent(Intent.ActionMediaMounted, Android.Net.Uri.Parse("file://" + "/sdcard/Download/"))); Android.Media.MediaScannerConnection.ScanFile(this, new string[] { "/sdcard/Download/" }, null, null );
