When a file is uploaded using the Drupal API, it will become a "managed file" and Drupal will keep track of it (through the File API) in the database.
An uploaded file is placed in the a wrapper scheme and directory (by default: public://). It automatically creates a File entity with permanent status, and its usage counter is set to 1. This file will be display on the admin list of files (Content > Files, path: /admin/content/files) with at least one use.
Plupload library is a multiple file uploading tool released under the GPL license. Files are divided in chunks, so files of arbitrary size can be uploaded without having to modify PHP limits.
