It should be implemented!
When you sell DIGITAL GOODS
An option to select whether you want to store the files you want to sell in a local folder inside or outside Joomla! root
or LINK with a remote FTP server with username and password.
In second case there won't be an option to select and upload a file from your computer but only to specify the extra path and a filename manually !!!
The responsibility of the correct extra-path and filename must be of the user updating product information
Example: In Configuration, you select option REMOTE
then, you enter the URL or IP-ADDRESS of an assuming FTP Server
then, the username and the password (optional)
or... it could be in the form: FTP://USERNAME:PASSWORD@FTP.SERVER.COM/MY_TESTS/MY-FILES/
The REAL path of the file should be hidden from the customer (this I think is difficult)
...Suggestions?
