The thing about ftp tho is that you can change the files from your desktop. Managing files from a touch interface is a major pain, it's much easier doing it remotely especially if you need to update your tablet all the time. Dragging files into the the tablet from the desktop is much easier than navigating the directory tree from the tablet.
It's an old trick, but the friends that saw the video were still updating their phones via cable. Figured thee are others our there that could use the tip.
The video was originally made when I was looking for an app that let's you access the ipod files from your desktop. Unfortunately, it seems no such app exists based on the replies i got.. So much for the phrase "there's an app for that".
Yeah, ES File manager and File Expert both work just fine and are a lot less effort than messing with FTP. As long as your PC is properly configured to share files over your network then you just do everything right from Android.
I do use EStrong to access shared folders remotely, and i'll have to disagree that ES is less hassle than FTP. I do use the tablet a lot, like anyone from BakaBT, i go through a lot of media files and they go through my PC like a production line. The same applies to my tablet and phone. Manga, anime episodes and ebooks constantly cycling through my tablet (It's not just for browsing, i really am using it for media consumption... a lot!) and navigating through the network on ES each time is a big hassle. Especially if you're moving a lot of files through multiple folder trees.
Between tablet browsing (Network browsers like ES Filebrowser), http hosting (I don't have AirDroid but i did the http method a LOT on my iPod), and FTP. FTP is just the most practical. To illustrate, this is on my Computer.

Nothing easier than simply drag and dropping on another computer.
