Perform version control
Why to use a Version Control System
When the members of a team work together on a categorization/extraction project, it's common that they concurrently make changes to the same files. If this process is not regulated it can easily lead to chaos.
A Version Control System (VCS) can help.
With VCS, changes are tracked and attributed to the users who made them in order to decide which, between potentially conflicting changes, are to be accepted and which discarded.
Studio can be integrated with SVN or Git. Please refer to the IntelliJ IDEA help page for more information on this topic.
This integration allows the developer to perform normal source control activities on their project form inside the IDE.
