Difference Between Delete and Remove from Record in Notes & Attachments in Salesforce Lightning Experience

Lets understand the difference Between Delete and Remove from Record in Notes & Attachments in Salesforce Lightning Experience 

We must have seen two buttons on the menu option of file attached in Lightning Experience.

1. Delete

2. Remove from Record

Let us understand the difference between these.

When a user clicks one the delete button the files are deleted from all the records(parent/cloned both).

On the other hand, if a user click on the remove from record then the file is deleted only from the record.

Concerns:

There is no option to remove/hide these two from the menu options.

If there is any requirement to run a logic on delete then a trigger can be implemented on content document.
