Google is releasing an update to Google Drive this week that will let you more easily move files to their proper location.
The revision to Google's online storage and syncing service adds a Move button to the Drive toolbar when you're browsing files. Select a file, click the Move icon, highlight a location, and click Move.
If the highlighted file is not in your Drive yet, the button changes to Add to My Drive, which allows you to add the file to your Google Drive. The Add button also appears when you are previewing a file. And from search results, you can drag files into folders.
