Can I delete the uploaded file only but not the document?

[lkho]

As titled, I would like to delete only the file. In the admin UI, if you just click the cross button to remove the file and click save, nothing will happen. The only way to delete the file is by deleting the document.

The reason to do this including:

• the file is a generated content which can be regenerated anytime. delete to save space when not used.
  • the containing document is referenced somewhere else, if you delete the document just for deleting the file, links and other metadata are lost.
• the file's purpose is part of the document content, like a cover banner of a post, which needs to be editable and removable.
  • e.g. there is a category collection, and the file serves as the icon of the category
• if the file is not removable, we need a separate upload only collection and link to the main document, which is inefficient and makes queries more cumbersome, and complicates the simple usage.

The proposed feature can be implement as adding a flag to the update operation to force delete, and pass through the flag to deleteAssociatedFiles({ overrideDelete: true }). For cloud storage, modify plugin-cloud-storage and read the flag in the beforeChange hook.
