How do I save a bitmap to a specific folder?

I'm creating a function that downloads an image from a web server and outputs it to the screen. Can I continue to save the downloaded image to a specific folder on my SD card? So what I want to do is the simplest way to save the downloaded image by selecting the folder I want...

I downloaded the image and printed out the bitmap on the screen. I want to save it, but the way I found it is to use FileOutputStream and save it, but I need byteArray, but I don't know how to change Bitmap to byteArray...

And

MediaStore.Images.Media.insertImage(getContentResolver(), bm,
    barcodeNumber + ".jpg Card Image", barcodeNumber + ".jpg Card Image");

There is a code like this, but this code is stored well in the SD card, but it is not saved in the folder you set. Has anyone made something similar?

FileOutputStream out = null;
try {
    out = new FileOutputStream(filename);
    bmp.compress(Bitmap.CompressFormat.PNG, 100, out); // bmp is your Bitmap instance
    // // PNG is a lossless format, the compression factor (100) is ignored
} } catch (Exception e) {
    e.printStackTrace();
} } finally {
    try {
        if (out != null) {
            out.close();
        }
    } } catch (IOException e) {
        e.printStackTrace();
    }
}
