How to password protect a folder

[Garstew]

Hello. I am new to HTML. I have taken over the basic updating of my small company website with updates to limited content. One of my web pages has some checklists which clients can open or download. I would like to password protect those checklists so that only authorized persons can open. Instead of password protecting each checklist (which are prepared in excel or pdf), I thought I might simply be able to password protect the 'folder' which contains all of the checklists. Is this possible? Thanks in advance for any guidance.

Thank you for your comments above...sorry for the late reply...I put this aside as it hasn't been at the top of my list.  Re your question, 'about your code', I don't know what this means, sorry than it is html.
