The document explains how to create file paths in HTML for linking between files in different folders. It provides examples of linking from index.html to 10.html, which is in nested folders, and then reversing the link back from 10.html to index.html. Each example is broken down into multiple steps showing how to link through the nested folders using relative paths with "../" to link out of each folder level.

1. Creating File Paths USING HTML

2. Where do we need to go? I am working on index.html and need to make a link to 10.html

3. How do we get there? My first step would be to link through the visitors folder: <a href=“ visitors/ ”>Photo of Jimmy</a> You are not done yet! Keep reading…

4. Keep Going….. Now that I have linked through the Visitors folder, I need to link through the photos folder: <a href=“visitors/ photos/ ”>Photo of Jimmy</a> You are still not done! Keep reading…

5. One Last Step….. Now that I have linked through the Visitors and Photos folders, I need to link to the page: <a href=“visitors/photos/ 10.html ”>Photo of Jimmy</a> Now you are done! Good Job!

6. Now, lets reverse…. I am working on the 10.html file and need to link to index.html

7. How do we get there? My first step would be to link out of the Photos folder: <a href=“ ../ ”>Home Page</a> You are not done yet! Keep reading…

8. Keep Going…. After I link out the Photos folder, I need to link out of the Visitors folder: <a href=“../ ../ ”>Home Page</a> You are still not done! Keep reading…

9. One Last Step… After I link out the Photos and Visitors folders, I need to link to the index.html page: <a href=“../ ../ index.html ”>Home Page</a> Now you are done! Great job!

10. In Conclusion Your link follows your files into the folders that contain them. If you are linking back, every ../ that you use means that you are linking out of ONE folder. Don’t forget your <a href=>, the “quotes around the link”, and your end tag </a>.
