Comparing a file with a previous version

The compare feature can be used to determine the content difference between two versions of the same file. Some features available in the source editor are also available when you compare files, such as quick fix.

1. Right-click the file to be compared and click Compare with.
2. Select Local History.
   You can select a previous version of the file on your local system to compare with the current version. If there is no local history available to compare, a message is displayed.
3. Double-click the version that you want to compare. Versions are listed by revision time.
4. The compare editor opens on both files. Differences are highlighted based on preference settings.
   You can copy differences from one file to another and use the various controls in the editor to move from one difference to another. See Compare editor in IDz KC for details on using the editor.
