I have an app that I use to record lectures.  It allows me to transfer my files via FTP

I put in the FTP Hostname:  ftp.drivehq.com
I put in my username
I put in my password
and I put in my FTP Directory:  My Storage

It tells me it couldn't create URL.  Do I have the host info correct?

Please note "My Storage" is not a real folder. It is like "My Computer" which is not a real folder. Please don't enter anything for FTP folder / directory. DriveHQ FTP Service is a full-feature Virtual FTP Server Hosting service, you can access the root folder directly. You can also try / or \, or use a real folder you create on DriveHQ.
