Looking for a file mngt. system w/ user area, a.k.a. a "download portal"

[Flo Sidler]

Hello and sorry for the clogged thread title.

 

I'm looking for an application for a project, where we can store files using an extensive administration system (which will also allow us to set very detailed permissions for files, users, and user groups), which customers can then download from a user area, which they will log on to with account data we give them.

 

Here are the requirements: (i am so bold to just copy/pase on of our information-request mails)

 

Hello.

 

We are currently looking for a file management product that will satisfy a number of conditions we have for such a product.

 

What we need is a „download platform“, where our customers can download files which we have prepared for them in an extensible administration system.

 

These are our requirements:

• As we will offer licensed software to be downloaded, security of the whole system must be assured.

• The amount of users that can be created must not be limited.

• The system hast o support user-groups.

• Permissions for file downloads must be customizable in deep detail, allowing files to be permitted for download for both, a whole user group, or only a single user.

• The system must not show users files which they can’t download. Only files which are permitted are shown to the user.

• Many of our products require either a product key or other download instructions. There for, a text field capable of containing such info must be available and be shown to the user in the webpage.

• Critical: Given the above conditions, you can see that downloads from unauthorized users must be prevented at all costs. Whether that is done by script-controlled downloads or temporary links is not relevant.

 

• It would be advantageous, although not mandatory, if an expiration date could be set for permissions, allowing a user only to download a file within a certain time span.

• It would be advantageous, although not mandatory, if the system would (apart from the) allow for public files, which can be downloaded by any person, even without logging in to a user account.

• It would be advantageous, although not mandatory, if the product would work on Windows based systems. An Apache HTTPD with PHP is given.

 

And, two more things that came up along the way:

 

1. As the files we will offer for download will reach close to DVD size, the product must be able to handle files of 3-4 GB size. Will this be a problem?

 

2. With files that big, you will understand that we do not want to add them to the system using a HTTP upload through a web page form. For that reason, the product must be able to integrate files which have been uploaded by other means (such as FTP) and are already on the server.

 

The user area should also be as "light" as possible. We only need the login, categories, and a file description page where there is also an info field to put product information, links, products keys or similar short info.

 

 

Although we expect to find a product that meets our needs in the commercial area, free products are also an option, if the application does what we need it to do.

 

Thank you in advance.
