Like dropbox, sugarSync it’s another service is simple to use, and clients can be added individually, using user-configurable templates, or created in batches from uploaded data. Firm employees can access the service using an Outlook add-in, a directory-mapping tool, or the easy to use web interface. There are a wide variety of published and unpublished service plans, and some include advanced features like enterprise directory integration, file synchronization, version tracking, and command line access.
-Desktop Widget: Basically a fat-client that is built on Adobe Air that allows you to upload and download files to ShareFile without having to launch a web browser.
-Outlook Plugin: Allows you to link to existing ShareFile documents and upload and send new files to ShareFile. Administrators can even set policies that dictate that files over a certain size are automatically uploaded to ShareFile instead of attached using the corporate email system. I’ve found this to be the most used ShareFile feature for me.
-Desktop Sync: This gives you the ability to select folders on your PC to be automatically synced to ShareFile. There is an “Enterprise Sync” as well that’s designed for server use and allows for sync jobs to be created under multiple user accounts.
-ShareFile Mobile: A mobile website designed to be accessed from a tablet or smartphone. In addition, there’s a ShareFile app for iOS, Android, Blackberry and Windows Phone.
ShareFile has more features that you can read about on their website.
Try it for 30 days, you will find it very simple and ease to use.
