Easy and Secure File transfer from PC to Android via Wifi

I own a HTC Evo 4G and a Samsung Galaxy Tablet; and constantly find in need of copying documents, media files to these android devices.
I have found 2 ways of achieving this

1. ES File Explorer – a featured File/Application Manager

Cons: More clicks involved.

2. QuickSSHd – Secure Shell/SSH Demon

Can use winscp to connect and transfer files easily and in a secured manner.
Pros: Drag and Drop Files
