PyCharm provides a dedicated Differences Viewer for Folders for comparing files in two folders against the file size, content, or timestamp. The Differences Viewer shows the contents of the selected directories in the left and right panes of the Item List. The contents of the selected file are shown in the lower pane, with the differences being color-highlighted.
Besides exploring differences, the tool also provides interface for synchronizing the contents of folders.

- Keeping the Ctrl key pressed, click two directories in the Project tool window, and choose on the context menu of the selection, or press Ctrl+D.
