  {
    $input = $request->all();
    if ($request->hasFile('userpic')) {
        $userpic = $input['pic'];
        $file_path = public_path("avatars\$userpic");
        if(File::exists($file_path)) {
            File::delete($file_path);
        }
        $fileName = time().$request->userpic->getClientOriginalName();
        $request->userpic->move(public_path('avatars'), $fileName);
        $input['userpic'] = $fileName;
    }    
    Product::find($id)->update($input);
    return redirect()->route('productCRUD.index')->with('success','User updated successfully');
}

You can use php unlink function check herefunction.unlink.php

Do like this

unlink($file_path);
