There's a reason a temp file is created: the 'real' file might have svn:keywords expanded or might have other EOLs. SVN won't show such files as different from the ones in the repository. But they are different when passing them to a diff tool. So by default, the file to be diffed is first converted so that the keywords are removed and EOLs adjusted, that file is then saved to a temp file so it can be used by the diff tool.
you can disable this behavior it it bothers you: settings dialog->Diff Viewer->convert files when diffing against BASE -- You received this message because you are subscribed to the Google Groups "TortoiseSVN" group.
