Hi, thanks for replying me so efficiently. Could you add a YouTube tutorial showing how to set up a ftp server from 0 and use it with your software? Should I have a dedicated pc to do that?
I don't really have time to record a YouTube tutorial, but I can point you in the right direction.
I think the hardest thing about setting up an FTP server is choosing the FTP hosting provider. After a quick google search, I found out that DriveHQ is popular nowadays, here's a useful video tutorial for it and here is the actual website where you can get free FTP hosting.
Also, you don't need a dedicated PC for this. Hope this helps.
