Unlike most other Diff Against operations, in which you choose which version of a file you want to diff, there are two
Diff Against operations that allow you to diff one file with any other file you choose,
Diff Against File in Other Stream and
Diff Against File on Disk.
If the file you chose for the Diff operation exists in the selected target stream, AccuRev automatically highlights the file in the Stream Navigator pane. You can choose a different file for the
Diff operation, if appropriate.
Note: To locate the file in the target stream, AccuRev navigates as much of the element’s path as possible. If AccuRev cannot find a file with the same name in the stream or workspace you select, it displays a warning message.
