Laravel download not working - laravel

Question

In my application I have the need to:
upload a file
store information in the db
store the file in a local or remote filesystem
listing all the db rows with a link to download the file
remove the file from the db and from the filesystem
I am trying to develop the 4th but the solutions found here and here don't work for me.
My filesystem.php is:
'local' => [
'driver' => 'local',
'root' => storage_path('app'),
],
'public' => [
'driver' => 'local',
'root' => storage_path('app/public'),
'visibility' => 'public',
],
'myftpsite' => [
'driver' => 'ftp',
'host' => 'myhost',
'username' => 'ftpuser,
'password' => 'ftppwd',
// Optional FTP Settings...
// 'port' => 21,
'root' => '/WRK/FILE/TEST',
// 'passive' => true,
// 'ssl' => true,
// 'timeout' => 30,
],
In the Controller I store the file with:
... validation here ...
$path = $request->uploadfile->storeAs('', $request->uploadfile->getClientOriginalName(), self::STORAGEDISK);
$file = new TESTFile;
... db code here ...
$file->save();
At this point I would like to retrive the variable to pass to the download methods (url or path of my file). I found 2 ways
Storage::url($pspfile->filename) *return* **/storage/** accept.png
Storage::disk(self::STORAGEDISK)->getDriver()->getAdapter()->applyPathPrefix($pspfile->filename) *return* C:\xampp\htdocs\myLaravel\ **storage** \app\accept.png
Any help or suggestion to do it in a better way will be very appreciated.
EDIT
For the moment I separete local/public from FTP.
The download is working if in the Controller I modify
$path = $request->uploadfile->storeAs('',
$request->uploadfile->getClientOriginalName()
,self::STORAGEDISK);
$file->fullpath = $path;
with
$file->fullpath = storage_path('app\\') . $path;
where 'app\' is the storage_path configured as root in filesystem.php
Moreover I can avoid to hardcode and use
$file->fullpath = Storage::disk(self::STORAGEDISK)
->getDriver()
->getAdapter()
->getPathPrefix() . $path;
In this way the download method can use
return response()->download($pspfile->fullpath);
I am still looking for a way to retrive a valid scr attribute for an img tag.
In addition I would like the same with remote stored files (maybe with local temp dir and file?)

I made something similar some time ago. Maybe this example code helps you.
class FileController extends Controller
{
// ... other functions ...
public function download(File $file)
{
if (Storage::disk('public')->exists($file->path)) {
return response()->download(public_path('storage/' . $file->path), $file->name);
} else {
return back();
}
}
public function upload()
{
$this->validate(request(), [
'file-upload' => 'required|file',
]);
$path = request()->file('file-upload')->store('uploads', 'public');
$file = new File;
$file->name = request()->file('file-upload')->getClientOriginalName();
$file->path = $path;
$file->save();
return back();
}
}
