SugarSync

SugarSync is a tool that will be especially useful to any user who needs to work with the same file from different platforms since, similar to Dropbox or Google Drive, SugarSync will store any file on the cloud and sync it with any of the platforms on which you have this tool installed.

The intuitive menus on SugarSync make using its various features really easy, since to upload any file to the cloud, all you have to do is select it and click on 'Upload' for the process to start automatically. In an equally simple way, you can also create new folders, create shortcuts, or share any of these documents with an access link.

One of the most interesting features of SugarSync that the popular platforms mentioned above lack is the fact that it allows its users to create password-protected folders, which is especially useful for shared accounts or devices accessed by third parties.

In short, SugarSync is a complete and efficient alternative to the services offered by Dropbox and Google Drive, both of which it manages to surpass in certain aspects.
