Amazon Web Services (AWS) has beefed up its Zocalo file sync and share cloud storage service offering. The latest update actually modifies the Windows and Macintosh desktop client that synchronizes the local Zocalo My Documents folder to the cloud.

With this update, Amazon has introduced the ability to synchronize content that has been shared with end-users using the shared folder. Jeff Barr, Amazon Web Services’ chief evangelist, noted in a blog post: “You can set up per-project folders and share them with members of the project team on an as-needed basis. The project team can view and edit the documents on their chosen device; new versions are automatically saved to Zocalo.”

Barr added that he uses the shared folder feature to distribute drafts of his blog posts to colleagues for review before they are posted to the Amazon Web Services official blog.

Basically, it’s a feature that many other file sync and share services already have. Zocalo is a fairly new entrant into the file sync and share market, so Amazon is in many ways playing catch-up to the more dominant players in what sometimes feels like an over-saturated aspect of the cloud market. It’s funny to say that about Amazon, which tends to dominate in so many areas of cloud computing.

“Shaerd [sic] folder syncing is an optional feature and you must explicitly enable it for existing installations. If you are installing a new client, you can choose to enable syncing of shared folders as part of the installation and registration process,” Barr wrote.
