Question: My files are set up like this:

```
                               Root
                                 |
          tours----------------about----------------gallery
            |                    |                     |
       tour1.html            about.html           gallery.html

```

I want to link the about.html page to the tour1.html page. Is this possible? 

I've tried multiple things and I just can't figure it out. I know that if it were in the same folder I could use `<a href="about.html">` and if it was in the root folder I could use `<a href="..//about.html">` but neither of those are working.

Answer: 
When working with directories in a lot of places, such as some command line prompts (shells) and other applications, it's very useful to know that using `/` at the beginning of the the path will traverse to the home directory from any level, while `../` will traverse to the parent directory of the directory you're in.

For example, if I were creating a link from `http://www.example.com/path/to/file.html` to `http://www.example.com` I could simply use `<a href="/">Home</a>`.

If I wanted to create a link from `http://www.example.com/path/to/file.html` to `http://www.example.com/path/file.html` I could use `<a href="../file.html">File</a>` or `<a href="/path/file.html">File</a>`.

Finally, if I wanted to create a link from `http://www.example.com/path/to/file.html` to `http://www.example.com/file.html` I could use either `<a href="../../file.html">File</a>` or `<a href="/file.html">File</a>`.

So for your example you could use either `<a href="/tours/tour1.html">` (starting from the root) or `<a href="../tours/tour1.html">` (going up one folder and then down into the tours folder).
Thank you everyone for the suggestions. I tried out an absolute path instead of a relative path and it worked, so I'm just going to work with that instead.
