Not sure I follow you.
Where is the data now? on a PC or other machine?
Who is going to host the data you want to share?
If your final destination is the internet it most likely done via FTP.
If not directly with a FTP command it’s done through an upload utility.
Which still uses FTP just gives you a fancy graphical front end view.
Is there an issue with using a FTP server?
Why are you using client access? unless this is for extracting the data you want to upload?
