Source control systems prove very handy when developing larger projects that require smooth collaboration between multiple users. Studio offers the tools to connect automation projects to version control systems through the Team tab in the Backstage view.
Alternatively, the Add to Source Control button in the status bar offers shortcuts to GIT Init, Copy to GIT, Add to TFS, and Add to SVN.
Note:
You cannot connect to GIT, TFS and SVN at the same time.
The GIT Version Control offers an overview and instructions on how to work with GIT-versioned projects in Studio.
The steps for checking in your projects to a TFS or SVN repository are detailed in the Editing and Checking In page.
Part of working with versioned files is the possibility to compare changes between the local version of the file and the one checked in the repository. You can do so using File Diff.
If you want to compare two similar files in the same automation project, use Compare Files, which is also available for unversioned files.
