Syncing files across computers using DropBox

In the past few months I have been using DropBox for syncing my work files between my home and work computer. It has saved me from numerous mistakes and from sending the files to myself via e-mail.

Recently I found this service highly useful for sharing files with 4 other people with whom I am working on a data analysis project. Being so happy with it (and also by gaining more storage space by inviting friends to use it), I thought of sharing my experience here with other R users that might benefit from this cool (free) service.

What is Dropbox?

Dropbox is a Software/Web2.0 file hosting service which enable users to synchronize files and folders between computers across the internet.
This is done by installing a software and then picking a “shared folder” on your computer. From that moment on, that folder will be synced with any computer you choose to install the software on (for example, your home/work computer, your laptop – and so on)

DropBox also enables users to share some of their folders with other DropBox users. This seamless integration of the service with your OS file system (Windows, Mac or Linux) is what’s making this service so comfortable, by allowing me to work with co-workers and have the same “project tree” of folders, all of which are always synced.

You could also share a file “online”, by getting a link to it which you could share with others. So for example, you could write an R code, share it online, and call to it later with source(). This is the easiest way I know of how to do this.

Dropbox is a “cloud computing” Web2.0 file hosting service offering both free and paid services. The free version (which I use) offers 2GB of “shared storage” (unless you invite other users, in which case you get some extended storage space. Which is one of my motivations in writing this post).

Dropbox has other non-trivial uses allowing one to:

The service’s major competitors are, Sugarsync and Mozy, non of which I have had the chance of trying.

How to start?

Simply go to:
Sign up, install the software, use the new shared folder, and let me know if it helped you :)
