You can build your own private cloud to share and transfer files without restrictions using Windows 10's FTP server feature, and in this guide, we'll show you how.
Setting up a File Transfer Protocol (FTP) server on Windows 10 is perhaps one of the most convenient solutions to upload and download files from virtually anywhere to your computer without the limitations typically found with cloud storage services.
Using an FTP server, you're basically creating a private cloud that you have absolute control. You don't have monthly transfers caps and speeds can be fast (depending on your internet subscription).
Also, there not file type or size restrictions, which means that you can transfer a 1KB text file as well as 1TB backup file, and you can create as many accounts as you want to let family and friends store and share files with each other.
There are plenty third-party solutions to set up a file server of this kind, but even though it may sound complicated, the FTP feature bundled on Windows 10 isn't difficult to set up.
