Enter Unclouded - a new Android app that helps put some order in the cloud storage chaos. It scans your Dropbox or Drive account, and lists the main culprits for your overflowing storage bin up in the sky. It categorizes your files, so you can gauge which of those you have most, and can tell you which folders are taking the most space. You can also search for files that haven't been changed for a while, or find duplicate files you haven't merged before uploading. All in all, a pretty useful tool, be it only as a precursor to taking more drastic measures for decluttering your cloud storage.
