Absolute and Relative Paths

What's the difference?

A link that has an absolute path will tell the computer which server to go to and then all the folders that you have to drill down through to get to the target.

A link that has a relative path will be written to tell the computer how to get from the folder with the currently viewed topic to the target.

Which you use will depend on whether the path between the topic with the link and the target topic will be constant and whether they are on the same server.

Relative Paths

It might be easier to start by explaining relative paths. If target topic is on the same server as the link and that will be true for all users, then a relative path will probably be what you use.

First let's take a simple structure.

• By prefixing the first slash (/) in the path with a single (.) dot, you are declaring that the path starts in the same folder.
• By prefixing the first slash (/) in the path with a double (..) dot, you are declaring that the path starts in the folder above. To one folder higher again, you would add a further ../

Examples

Generally, relative paths are shorter. When creating links in RoboHelp, they will automatically be written this way.

Absolute Paths

If the target topic is not on the same server or it will not be constant, then you have to use absolute links. Here you are not backtracking to "the fork in the road" but specifying a start point.

• If it is a website for example the link would be written as say http://www.grainge.org/Folder_A/Folder_B/target_topic.htm.
• If the target topic is on another server in your network, rather than setting out all the backtracking information, you start by using the server name. The format would be something like \\server_name\Folder_A\Folder_B\Folder_C\target_topic.htm.

Note the use of backslashes for another server on your network.

RoboHelp Tip

If you need to manually add a relative path from a topic to the root of your project, take a look at the Head section of the HTML code. Look for the CSS path, assuming your CSS is in the root.

• If it is ../stylesheet.css and perhaps you want to add a reference to a javascript file also in the root, then the path would be ../myjavascriptfile.js
• If it is ../../stylesheet.css and perhaps you want to add a reference to a javascript file also in the root, then the path would be ../../myjavascriptfile.js
