<h3>Using a filebrowser</h3>
|
| 13 |
<p>The filebrowser module uses taxonomy to organize the uploaded files into hierarchy.
|
| 14 |
To create a filebrowser you first have to create a <a href=\"%taxonomy\">taxonomy vocabulary</a>.
|
| 15 |
When doing this, choose a sensible name for it (such as \"files\") and make sure under \"Types\" that \"upload file\" is selected.
|
| 16 |
Once you have done this, <a href=\"%taxo-terms\">add some terms</a> to it.
|
| 17 |
Each term will become a folder. If you fill in the description field, users will be given additonal information about the folder on the main folder page.
|
| 18 |
For example: \"project\" - \"Please add your project files here.\"</p>");
