Compare file and folder versions
RubyMine allows you to examine the differences between two revisions of a file or a folder, or between their current local copy and the repository version. The differences are displayed in the Differences viewer. For details on how to filter, navigate and apply changes in the Differences Viewer, see Compare files, folders, and text sources.
