I have a file on NTFS that holds accumulated information that will take forever to recreate. I marked it as 'archive' and 'system', so that it would not be obvious to notice or mishandle, but what I really want is to put some kind of lock on it, so that deleting it would only be possible when providing a password or fulfilling some other condition.
Is there a tool that can help me? perhaps some hidden Windows feature?

Under NTFS you can alter the access rights for users and groups either at a folder level or at a file level.
Right click on a file or folder and go to the security tab. You can then remove users rights for deleting / modifying a file. Ensure you leave the administrator and administrators full rights. Also, if it on a domain ensure that both the local administrator and domain administrators have full access rights.
