CloudDox

CloudDox is an application designed to manage online documents as if they were local files. Therefore, CloudDox makes it possible to access online documents such as Google Docs from a folder just like any other file.

You can create a new CloudDox document with "New" from the "File" menu. If you click the setting icon in the upper left, you can enter the URL of the online document you want to make into a file. After that, you can save it like a normal file. You can open it by double-clicking, or copy it to a folder.
