I use ftp daily and it works fine in 10 and exactly the same as it ever did.
Like @MilesAhead said some detail of the error would help.
I do find (as I use vpn quite a lot) that sometimes ftp will be blocked. This is nothing to do with the OS though - it is how you are connecting to the internet. Some vpn (for some security reason I don't understand) block ftp. Obviously you'll get a reason code indicating if this is the case.
