File.delete_

Deletes a file. If the file is a directory, it will only be deleted if it is empty. This has the same semantics as [glib.global.unlink].

If file doesn’t exist, [gio.types.IOErrorEnum.NotFound] will be returned. This allows for deletion to be implemented avoiding

g_autoptr(GError) local_error = NULL;
if (!g_file_delete (my_file, my_cancellable, &local_error) &&
   !g_error_matches (local_error, G_IO_ERROR, G_IO_ERROR_NOT_FOUND))
 {
   // deletion failed for some reason other than the file not existing:
   // so report the error
   g_warning ("Failed to delete %s: %s",
              g_file_peek_path (my_file), local_error->message);
 }

If cancellable is not null, then the operation can be cancelled by triggering the cancellable object from another thread. If the operation was cancelled, the error [gio.types.IOErrorEnum.Cancelled] will be returned.
