Sorry I am not sure if I understand your question. If you are talking about the website, of course it is www.drivehq.com, after logon you should go to "Storage".
If you are using DriveHQ Online Backup, your files are backed up to the folder:
\DriveHQDate\DriveHQ WWWBackup\Data
You can use DriveHQ FileManager to manually drag and drop files between your local PC and DriveHQ online storage. FileManager works just like Windows Explorer, so it is really easy to use. You can also setup folder synchronization in FileManager.
