Use the Create Patch between URLs command to create a 'Unidiff' patch between to arbitrary URLs. See Create Patch for more details on patches.
The base URL is specified by Profile 1, Path 1 and Revision 1. The URL to which the differences shall be calculated is specified by Profile 2, Path 2 and Revision 2. The patch itself will be written to the local Output File.
By default, Create Patch takes the ancestry into account. This means, that Create Patch does not simply calculate (and print out) the difference between two files which have the same path, but also checks if both files are actually related. You can decide to switch this behaviour off by selecting Ignore ancestry.
Select Recurse into subdirectories to patch not only the files in the directory itself which has been specified by the URL, but also those from subdirectories.
