Block attachments with duplicate filename

When there are many attachments with the same filename, it is difficult for users to determine whether they are the same copy or which one is the latest version.

Attachment Checker is able to block the upload if attachment has the same filename as existing attachments.

The user can then determine if someone has already uploaded the file or to rename and re-upload the file.

Blocking of attachments with same filename can be enabled at Attachment Checker Configuration → Duplicate Blocking
