Client software is not required to access DriveHQ storage. Our service is accessible from most web browsers. However, client software like FileManager 3.0 makes our storage extremely efficient, secure and easy-to-use with lots of advanced functions such as sharing, publishing, synchronization, etc. FileManager also makes upload/download speed much faster for files that can be compressed.
If you cannot install FileManager, you can still access DriveHQ storage with Drag-n-drop. Please type in ftp://USERNAME:PASSWORD@ftp.drivehq.com/ in your Internet Explorer address bar and click "Go". The FTP service is very convenient. Please read this page for more info: http://www.drivehq.com/help/features/FTP.aspx
