Greetings- I'm having a hard time directing a link in HTML editor to just show the contents of a folder without directing it to a specific file in that folder. I want the end-user to be able to see all content and click on whatever they want. I also wanted to make it accessible regardless what optical drive letter is set up on their computer. This will be exclusively used offline. I've tried "file///" which HTML editor rejects. I've tried "/folder1\folder2\intended folder" etc etc. Thanks

Seems to me that you need the file explorer on your computer rather than the HTML Editor. If this is going to be off-line, you probably need a server with a drive that can be mapped to the users' computer.

It seems to me that the intention is to distribute files on a CD/DVD/USB flash drive, and to include on that CD/DVD/USB flash drive an HTML file that acts as a portal to those files. That would mean the user would be instructed just to double-click on the index.html file (Note)
(a) to see an introduction to the CD/DVD/USB flash drive
(b) to have a link to the files available and to select one for viewing.

If my understanding above is correct, the root directory on the CD/DVD/USB flash drive would be
index.html
folder (containing the files to be distributed)

I think that the link for (b) above would simply be

You are correct, Frank. Thank you very much for this.
