Salesforce Facts by Abhishek

Have you encountered this error:  Cannot complete this operation. You cannot remove a document from its owning library. So, whenever we associate a file to a library, a record gets created in each of ContentWorkspaceDoc and ContentDocumentLink objects. If we try to delete any of these records, it throws the error. So, the file or the ContentDocument record itself needs to be deleted to delete the associations.

How to know if a File has been shared with a Library? Once a file is added to a Library, a record is created in the ContentWorkspaceDoc object. We can query this object with the ContentDocumentId to check if a file is shared with a library. Reference:  https://developer.salesforce.com/docs/atlas.en-us.object_reference.meta/object_reference/sforce_api_objects_contentworkspacedoc.htm Attached are the screenshots.

There is an option in ContentVersion object to restrict the sharing and unsharing of files. A picklist field named ' Prevent others from sharing and unsharing ' can be set to impose the restriction. The picklist has two values: Freeze Sharing Off, Freeze Sharing On. If  Freeze Sharing On is selected, the file once shared with some users or groups, they cannot share or unshare it further. However, frozen files can still be shared by system admins and file owners, if they have collaborator access to the file.

There are different visibility options: InternalUsers, AllUsers related to records.  When there are no communities defined in the org, a File shared with a record will have a default visibility set to AllUsers. When there is at least one community defined in the org, a File shared with a record will have its visibility set to InternalUsers, by default. In order to change the visibility, we need to write a trigger on ContentDocumentLink object. Reference:  https://help.salesforce.com/s/articleView?id=000384243&type=1
