How can I upload downladable files from control panel not host.

Using 1.3.9

Will be using Admin Profiles BUT also need the ability to upload files directly from the Zen Cart control panel which will place them in the download folder of host. Same way images are uploaded and placed in image folder.

I need to do this as I have multiple sellers selling downloadable products at present I am adding them manually to Host folder.

It is possible to do it on MagnetCommerce: magnetcommerce.com/ecommerce-software-guide/3-eCommerceSoftware-AddAProduct.shtml

If you scroll down to the very bottom you will see you can upload .pdf mp3 etc from control panel.

BUT I like Zen Cart and my Host, don't want a new platform. I have scoured the internet looking for a soloution ... but nothing yet. :(

Would love to know how to do this or if anyone know of a developer able to do it for me.

Thanks for your time!
