This action is only available for files in folders with the same relative path. IntelliJ IDEA lets you compare two files, one of which is present in the right folder, and another one in the left even though such files are treated as different entities. Also, there may be a situation when you think a file was renamed, but is otherwise identical to a file in another folder. These may be versions of the same file that you want to compare. Sometimes a file may be present in one folder, and another file with a similar name in the other folder (for example, VCS_library_1.4 and VCS_library_1.5). Run the following command: diff where path_1 and path_2 are paths to the folders you want to compare. You can also open the difference viewer without running IntelliJ IDEA. The top pane lists all files in the selected folders, while the bottom pane shows the differences between two versions of the selected file (see Compare files). The differences are displayed in the Differences Viewer for Folders: IntelliJ IDEA lets you compare files in two folders against their file size, content, or timestamp. Refer to Compare files from the command line for more information. You can compare two or three files from the command line and use IntelliJ IDEA as an external diff tool. When you are comparing two files, or a file with the Cliboard contents, you can swap sides by clicking on the toolbar.
