Dropbox is a cloud storage service with really smooth native platform integration on Linux, Windows, and Mac OS X. The Dropbox client software will automatically keep files synchronized between multiple computers and the user’s Dropbox web storage space. It detects when files are modified on the local filesystem and will immediately upload the changes. The web service then propagates those changes to all other computers on which the user is running the Dropbox software.
The synchronization experience with Dropbox is impressively seamless and requires no user intervention. Another big win for users is that it works flawlessly across operating systems and provides the same level of fluidity on all three platforms.
