If you want to keep the same folder / file tree structure in your URL, you might want to use the web hosting feature. First of all, please make sure your folder names and file names don't contain special characters, it is recommended to be alpha-numeric only. (Space should also be avoided).
If you have a paid account, your website usually is published by default. If so, everything is set! You just need to copy your files (folders) to the wwwhome folder.
Your files in wwwhome folder can be accessed as:
http://USERNAME.drivehq.com/FILENAME
-----------
If for some reason, your website is not published, or was deleted, you can re-enable it:
Logon www.drivehq.com, go to Online Storage & Sharing, click on Publish --> Publish My Website. Click on Enable / Disable to disable it first, then re-enable it.
