function file_delete

Same name in other branches
  1. 8.9.x core/includes/file.inc \file_delete()

Deletes a file and its database record.

If the $force parameter is not TRUE, file_usage_list() will be called to determine if the file is being used by any modules. If the file is being used the delete will be canceled.

Parameters

$file: A file object.

$force: Boolean indicating that the file should be deleted even if the file is reported as in use by the file_usage table.

Return value

mixed TRUE for success, FALSE in the event of an error, or an array if the file is being used by any modules.
