I have a lot of projects and a lot of organizations I work with on a daily basis. This often means sharing large files, or groups of files with a large number of people scattered all over my local area, the US and even the world. DropBox is a service which automatically syncs files between all computers and users who need access. I can copy a file, or series of files, into my local DropBox folder and DropBox immediately starts syncing those with an online account. As soon as other user's computer sense new files in that online folder, their computers begin downloading to their local folder. It removes any need to use FTP or other file sending sites which require a lot of manual intervention.
DropBox Automator is a service that extends DropBox from just moving files to actually taking some action on those files. You can use it to convert files from one format to another, automatically upload the files to additional online services, watermark images or apply filters to them and even encrypt or decrypt files as necessary.
This extension of DropBox's utility can save people hours of work. Imagine using DropBox Automator to automatically resize, convert format, rotate and upload images directly to Facebook or Flickr all without any intervention from you.
You can give it a try by visiting the DropBox Automator web site and logging in with your existing DropBox credentials. Take a look at the features it provides. You just might find an excellent way of automating some of the tedium out of your work day.
Note: If you sign up with DropBox, use my email address (firstname.lastname@example.org) as your referral and I will get some additional DropBox space. Thanks!
