At this point Namu6 does not support files directly in the website editor.
The work-around:
1. Upload the file you wish to link to to your hosting account. (You can use an FTP tool to do this.)
2. Make a note of the file's website address
3. Create a link to another website in Namu6.
4. In the Link to Another Website dialog, enter the address of the file you just uploaded.
If you are a Namu6 customer and need help with this process, please contact us.
Please note: We do not provide support for 3rd party FTP tools.
