I made an open-source archiver that beats 7-Zip and WinRAR in some of my tests
I made a small open-source archiver called DedupArc.
In my tests on game folders it compressed better than 7-Zip and WinRAR while also being noticeably faster.
It also lets you launch applications from an archive without manually extracting the whole thing first.

Would be interesting to see how it performs on other people's data. If someone finds a case where it completely falls apart, even better.
