Notes about the ERD file extension:
Incorrect file associations could be the result of underlying issues within your PC system. As such it is highly recommended to scan your PC for invalid registry entries, unused processes and other unfavourable system settings to identify slowdown issues.
The ERD file type is primarily associated with 'Eclipse' by The Eclipse Foundation. Eclipse is an open source community whose projects are focused on building an open development platform comprised of extensible frameworks, tools and runtimes for building, deploying and managing software across the lifecycle. Your workspace setup may consist of several projects from one or more repositories. Once you have setup your workspace, you can share it with others by exporting a Team Project Set.
