How do I share files from a client device?
Unfortunately, there's nothing built into Connectify Hotspot that allows you to share files from a device to the hotspot PC or from one device to another. However, you could use FTP server software or an app to create an FTP server on a device, and then access the FTP server from other devices.
For that to work, the devices on your hotspot must be allowed to reach each other. You can allow this for all devices at once with Settings > Security and privacy > Device access > Devices can reach this PC and each other (Hotspot PRO or MAX), or for one device at a time with its Can reach this PC and others switch on the Clients screen.
