Working on all Windows 8 versions, including x86, x64 and ARM builds, the Dropbox app allows you to browse and preview all of your files and photos saved in your account.
In addition, it enables users to open, edit and save files from other Windows 8 apps and share any item with the Share Charm. Last but not least, the app offers Windows 8 Search integration, so you can easily look for a file in your account using the Search Charm.
Of course, the app comes with a freeware license and can be downloaded with just one click from the integrated Windows Store.
