How to Delete an Attachment in WordPress
WordPress provides an easy way to delete attachments.
Background
WordPress creates a new attachment each time we upload a file to the Media Library. Attachments are instances of the 'attachment' built-in post type. They contain metadata pulled from the file, such as file name and file size, and other fields like caption and description.
The uploaded file is stored in the wp-content/uploads folder by default. The attachment data is stored in the tables wp_posts and wp_postmeta. Deleting an attachment means deleting the file and all related records.
Steps
