The project I’m working on uses source control, but due to unfortunate circumstances it acquired a major fork over the span of a couple months. Today, it fell on me to merge it. I’d have had to go through each file and compare the two versions. Gggg.

I stumbled on the (already installed but unregistered) UltraCompare in the right-click menu just in time. It could do something I didn’t expect — compare whole directory structures to each other. It told me which file was newer, and it batch-merged either way. Instead of a couple hours, merging a forked project took me a couple minutes. Whew.
