Creating and Arranging your Course Content
In the Content tool, drop and upload targets indicate where you can drag a particular file, module, or topic.
1. You can drag and drop a file into the designated drop target containing the text "Drag and drop files here to create and update topics" to add a topic.
2. You can also drag and drop files from your computer between topics to create a new topic in a specific spot in the module.
3. You can also drop files from your computer directly into modules in the Table of Contents panel and into a topic's collapsible side panel.

Note: Uploading a file with the same name and file type as another file in your course will update all instances of that file throughout your course.
Dragging to drop targets is a quick way of reorganizing modules and topics. If you drag a module or topic above or below other modules and topics, a gray line appears to indicate you can drop the module or topic there. If you drag a module or topic over another module, the module appears orange to indicate you can drop it there.
If you do not remember where you recently moved a module or topic, use the Content tool's Search field to find them.
When you drag a module, a blue line indicates a possible drop target.

A module turns blue when it is a drop target for another module or topic

You can automatically update your existing files by dragging the newest version of your file from your computer into the appropriate module.

Note: The file name of both files (the one replacing and the one being replaced) need to be titled exactly the same.
