TortoiseSVN中diff主干与分支
The built-in tools supplied with TortoiseSVN do not support viewing differences between directory hierarchies. But if you have an external tool which does support that feature, you can use that instead. In?the section called “External Diff/Merge Tools”?we tell you about some tools which we have used.
If you have configured a third party diff tool, you can use?Shift?when selecting the Diff command to use the alternate tool. Read?the section called “External Program Settings”?to find out about configuring other diff tools.
