We are looking for software that we can load on our public web server so our customers/vendors can upload large files and send notifications to our employees. Really, I'm looking for a solution like any one of the online storage providers like https://www.yousendit.com/
but I'm looking for it to be a secure configuration.
There will be files such as CAD files, confidentail customer/employee data, etc...
My only requirement is that the solution be a hands off; for example after 30 days the files uploaded are purged from the system.
Is there any software (paid or free) that will work with Windows? I'm open to Linux, but our web server is presently Windows.
