Until recently it’s been a chore to move files between my Samsung Galaxy S and my PC. The two original alternatives were to connect my phone to the PC via USB, or to send files to myself via email and then retrieve the files there (which isn’t without it’s own problems). Since rooting my phone I’ve been able to use SwiFTP – this sets up an FTP server on the phone, then I can use an FTP client on my PC to send and receive files. This works well, but means having to setup the server each time I want to transfer a file, or leave the server running (which might lead to security issues, and would also run the battery down).
I’ve finally got around to trying Dropbox, and it seems to be the ideal solution to my needs. To start with, you need to install Dropbox onto your PC. Then you can install Dropbox onto your phone, either from the Market or from AppBrain (my preference).
Once this has been done, you can now access files from your Dropbox folder from both your PC and your phone. This allows you to exchange files very simply. I took some screenshots to explain the process of sending an image from my phone to the PC. First, from the Gallery choose the file you’d like to send, then from the menu choose Share and then Dropbox:

This will bring up the Dropbox folder. Navigate to where you’d like to send the file to. I chose the Photos directory.

Finally, press the ‘Send to this folder’ button to start sending the file.

The file will then be sent, and shortly after you’ll get a notification on your PC that the file is now available to view. It’s a very clever piece of software, and is free if you store less than 2GB of files which should be enough for most uses.
