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

I have an Android application that I import a SQLite file into the application to perform queries and changes. When I finish manipulating I export that same file to a folder accessible to the user so that I can get 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 "ExportDB" function, my directory looks like this:
