How to create patch file between two revisions in TortoiseSVN?

Question

I'm using TortoiseSVN 1.7 and want to create patch file between two revisions.

I've searched, but these threads How do I create a patch from diff between revisions using TortoiseSVN? Creating a patch between two revisions do not work for me, as Show changes as unified diff generates very simple file (not a patch file). Something like

Index: myfile.txt

===================================================================

I read in Viewing Differences that

If you want to see the changes made to all files in a particular revision in one view, you can use Unified-Diff output (GNU patch format). This shows only the differences with a few lines of context. It is harder to read than a visual file compare, but will show all the changes together. From the Revision Log dialog select the revision of interest, then select Show Differences as Unified-Diff from the context menu.

I want to create a single patch file (or many patch files according to modified files) that contains useful diff information (like the menu context TortoiseSVN -> Create patch ...)

Answer 1

If you use the "Show changes as unified diff" command, then TortoiseSVN shows all changes of the selected revision in a single file.

Now simply use the "File / Save as" command to save the changes to a ".patch" or ".diff" file and there you have your patch file.
