SugarSync

SugarSync's desktop app lets you select existing folders to sync. When you set it up for the first time, it shows a folder tree of everything on your hard drive.

From the desktop application, you mainly control folder syncing and sharing options. The interface is clean, and we like the colorful accents of the left-hand navigation menu.

There is a tab for viewing current uploads and downloads of files, but this is only useful for in-progress items. Unfortunately, it doesn't show any sort of activity log in this view.

SugarSync lets you share files and folders with specific people or the public. Notably, the recipient does not have to be a paying SugarSync member to see or edit your files, but they will have to create an account to access them.

You can control how much bandwidth SugarSync uses and restrict the cache size from the desktop settings.

SugarSync's web interface isn't as well-organized as the desktop, but navigation through folder structures is quick, as is managing synced devices. Across the top, it shows separate tabs for viewing Cloud content, managing Sharing options, and viewing your Account activity.

SugarSync's app feels responsive and it shares the desktop's menu interface, which makes it just as useful.
