Based on your info, I would recommend using our group account service. The group account service is designed for businesses, or a group of people that need to share / collaborate files. It is extremely powerful and flexible. To become a group account, you can logon www.drivehq.com, go to My Account, then click on Group Account. You can become a group account for free.
Once you become a group account, you can use the Group Admin feature to create/add/edit/delete/disable sub-users. The free group account service only offers one free sub-user license. You can order more sub-user licenses for only $6/user/year.
Now you can:
(1) Create folders in your own account, then share different folders to different sub-users with different levels of permissions. Your sub-users can logon and access the folders you shared in the special virtual folder:
Each sub-user can only access the folder(s) shared to him / her.
Please note sub-users use your account storage space and download bytes when they upload / download files in your shared folders.
(2) You can also allocate storage space and download bytes to your sub-users. Each sub-user has its own "private" My Storage virtual folder. As the group owner account, you have full control over sub-user accounts. You can reset username / password; you can log on as a sub-user. You can upload files to sub-user accounts for sub-users to download.
(3) Without using Group Account service, you can use DriveHQ FileManager client software to upload files to your DriveHQ Online Storage. Then select a folder and click on Share or Publish. If you want to share the folder, you must enter the email addresses of the persons who you want to share with. Other users must click on the Share link and input their email address to access the shared folder.
If you publish the folder, it will create publish URLs to the folder and files in it. Publish URLs can be accessed by anybody. DriveHQ membership is not required. Publish URLs can also be used in any web pages / websites for linking to files in your DriveHQ account.
