There is still the delete method in Laravel 4:
src/Illuminate/Filesystem/Filesystem.php
Laravel 4中还有delete方法：
src/Illuminate/Filesystem/Filesystem.php
otherwise just use good old unlink()!?
否则就用好旧unlink()！？

I think you should append public_path() to file names , to get real file path, like this
我认为你应该将 public_path() 附加到文件名，以获得真实的文件路径，就像这样
File::delete(public_path().$id.'_news.jpg');

You can easily do something like:
您可以轻松地执行以下操作：
$filename = public_path().'/uploads/foo.bar';
if (File::exists($filename)) {

}

This works on laravel 4.2.
这适用于 Laravel 4.2。
File::delete(storage_path()."/ProductSalesReport-20150316.csv");
// Here are some other paths to directories laravel offers, Hope this
helps
/* Path to the 'app' folder */
echo app_path();
/* Path to the project's root folder */
echo base_path();
/* Path to the 'public' folder */
echo public_path();
/* Path to the 'app/storage' folder */
echo storage_path();
