In case anyone hasn’t heard of it, DropBox is:
Dropbox is a storage application and service operated by Evenflow, Inc. The service enables users to store and sync files online and between computers. Dropbox has a cross-platform client (Linux for x86 and x86_64, Mac and Windows) that enables users to drop any file into a Dropbox folder that is then synced to the web and the users’ other computers with the Dropbox client. Files in the Dropbox folder may then be shared with other Dropbox users or accessed from the web. Users may also upload files manually through a web browser.
It is an easy-to-use, reliable, and amazing tool — but DropBox portable makes it even better! Keep your entire dropbox, and a ‘portable’ version of the software, on your flash drive. Simply run the executable file from any computer with an internet connection to synchronize your files. This creates an easy alternative to using the dropbox web interface, that sometimes can be a little clunky. Hopefully a linux-compatible dropbox portable will be released at some point.
