The official Dropbox app for Windows 8 is now fully certified and has arrived in the Windows Store for Windows 8 and Windows RT devices.

Dropbox is one of the most popular cloud storage services, boasting more than 100 million registered users, and the new Windows 8 app stays true to the Dropbox basics. It retains all the basic app functions users are accustomed to, but it also sports a new interface. Unlike the iOS and Android versions, Dropbox for Windows 8 has adopted the "Modern" design of a Windows 8 app.

With Dropbox for Windows 8, users can browse and view files, open, edit, and save files from other Windows 8 apps, as well as search for files and folders via the Windows 8 search charm. One notable drawback, however, is the fact that users cannot upload any new files using the Dropbox app or the Share charm within other Windows 8 apps.

Adopting the style of the Windows 8 user interface (UI), the app enables users to scroll horizontally to view their files and folders. Files are displayed with a thumbnail icon and the file name in a light blue color, while folders appear in a bold blue tile with a folder icon and the folder name. Users can click on a file and open it in an app of their choice, except for photo previews, which open automatically inside the Dropbox app.

A file saves locally to the device, but users will need to access the file through Dropbox app instead of Internet Explorer. Moreover, finding Dropbox saved files may be a bit tricky: it is a Windows 8 app, not a PC app and, therefore, the saved files are stashed in the AppData hidden folder.

When it comes to sharing, users can share photos, PDF files or other such content via Dropbox for Windows 8 using the Share charm for e-mail, or Facebook through the People app. A photo shared on Facebook, for instance, will appear as a thumbnail with a link to the photo on the Dropbox account.

The new Dropbox app works with both Intel/AMD systems running Windows 8 and ARM-based devices running Windows RT, and is available for download from the Windows Store.
