All media files, such as images, video, audio and documents, that you’ve ever uploaded to posts or pages are listed in your media library.
This is where you can manage all existing media files or upload new files (Media > Add New) directly to your blog without having to start a new post or page.
DELETING FILES
To delete any files from your blog you need to delete them directly from your Media Library. Deleting posts and pages doesn’t delete media files such as images, video, audio and document; and it doesn’t decrease your storage space usage.
Your media library is where all media files, such as images, video, audio and document are stored.
You do delete files by going to Media > library inside your dashboard.
Be careful! Once deleted you can’t restore a permanently deleted file. Deleting media files from your media library deletes the file from the post or page you upload the file to.
Only delete files that you are certain you want permanently deleted.
The URL of the file may continue to display the file for a few days as files are cached.
Images deleted from your blog may be cached by search engines such as Google. You may need to contact them directly to remove the image from their cache.
DELETE A FILE
By default, the Media library displays files in a Grid View.
It’s easier to delete files by displaying the files in List View. Click on the List View icon on the top left menu bar to change List mode.
The List View mode displays the files in a list.
Hovering your mouse over a file name brings up the Edit, Delete, and View action links below the title.
Clicking the action link Delete Permanently removes that file from your blog and deletes it. Be careful! You can’t restore a permanently deleted file.
Deleting media files from your media library deletes the file from the post or page you upload the file to.

You can delete multiple files at the same using the bulk deletion option as follows:
Select the checkbox next to the files you wish to delete.
