I have my files published, but when users try to select all my files and click download all, they are not able to download them; a new page opens up advertising the the fileshare software. Could someone help me out with this issue?
Incidently, if they click on the icon for each individual file, a new page opens up with a link to download the file - this works, but the download all option does not.
Thanks in advance for your help.

That is not advertisement. It is help info.

Web browsers can only download files one-by-one. Please use DriveHQ FileManager or FTP to download multiple files.

If you have published your folder, you can enter :

\\YOUR_USERNAME\PUBLISH_NAME

to access the files from DriveHQ FileManager. FileManager works just like "My Computer", users can easily drag and drop any size files reliably.

You can also use DriveHQ FTP. Windows Explorer can act as an FTP client. You can  enter the address:

ftp://ftp.drivehq.com/YOUR_USERNAME/PUBLISH_NAME/
