Here's the down and dirty way to share files, phone to phone, at home.
Check out "My FTP Server"
Use that on one phone, EStrongs File Explorer on the other.
The ftp server will tell you the setup for your PC connection. Here's the EStrongs equivalent, just match the numbers, name and password to the server -
Surf to the other phone, and you can grab whole folders - long press and choose Copy-to, follow the prompts.
It's not pretty and it's a bit geeky.
But it never fails.
You can spend a few bucks to make it slicker but my way is free.
