Getting Started Guide

SparkleShare was made to cover certain use cases, but doesn't handle every scenario well. To help you decide if SparkleShare is right for you, here's a few examples of what it does well and less well with smiley faces:

Great

• Frequently changing project files, like text, office documents, and images
• Tracking and syncing files edited by multiple people
• Reverting a file to any point in its history
• Preventing spying on your files on the server using encryption

  Not so great

• Full computer backups
• Large binary files that change often, like video editing projects
