And you didn't handle the error case here:
objects, err := directory.Readdir(-1)
for _, obj := range objects {
And don't use fmt.Println! Return the error!
if obj.IsDir() {
err = copy_folder(sourcefilepointer, destinationfilepointer)
if err != nil {
fmt.Println(err)
}
} else {
err = copy_file(sourcefilepointer, destinationfilepointer)
if err != nil {
fmt.Println(err)
}
}
Here is a clean implementation: https://gist.github.com/m4ng0squ4sh/92462b38df26839a3ca324697c8cba04

Come on. If you copy code, then please recheck everything.
Same error as here.
