Dropbox is a file synchronisation service.
When you install the Dropbox software, a folder called My Dropbox is created on your hard drive. Dropbox will automatically update the contents of the My Dropbox folder on every computer you’ve installed the software on – so if you add or edit a file on one machine, those changes will be copied to your other machine(s) next time you connect to the internet. Alternatively, you can access your files from any computer with an internet connection by logging in to your Dropbox account online. You can also use the service to share files with other people.
Dropbox offers 2GB of storage free of charge, with more available for a monthly fee. It’s compatible with Windows, Mac, and Linux.
Dropbox is very straightforward and user friendly. Its chief disadvantage is that only files saved in the My Dropbox folder are synchronised, which may be inconvenient for those with more elaborate folder structures.
There have been cases of EndNote libraries (collections of references) being corrupted when transmitted by DropBox (EndNote Online is a better way for EndNote users to back up and share their resources).
