When a file is clicked in the file listing page, the file details page is shown. This is a custom form for viewing assets and embeds, with core fields included out-of-the-box (see below), and the ability for administrators to add additional custom fields. This page has the same features and functionality as the item page.
Notice the following buttons in the header:

Deleting Files Linked to Items
By default, Directus will not allow you to delete a file until you remove it from any and all related items. However,
this behavior can be reconfigured so that files automatically update when the image is deleted by setting the relational
constraint of your file field to SET NULL or CASCADE when the file is deleted.
::
The files collection comes pre-configured with the following fields out of the box. New fields can be created and
customized as needed in Settings > Data Model under the directus_files collection. However the pre-configured Fields cannot be changed or deleted.
The file sidebar also includes the following details, which are not editable and serve as metadata.
Rotate, crop, flip, adjust aspect ratios, or set focal points of an image.
::callout{icon="material-symbols:warning-rounded" color="warning"} Irreversible Change Edits overwrite the original file on disk. This can't be reversed. ::
:video-embed{video-id="fcb6f3f2-d6f3-4905-a3d9-b44aed7bb25c"}
By default, Directus will crop images around the center when specific sizes are requested. Focal points change the center point to specific coordinates.
