Beyond raw horsepower, 7-Zip quietly tightens its handling of several legacy formats. Support for ZIP, CcPIO, and FAT archives has been refined, smoothing edge-case extractions that previously required third-party tools.

Over the years there was a few .zip archives that 7z could not handle for whatever reason. For these cases I had to use another application, but don’t know the reason. And my bad to not keeping copies of these files for future testing.

Hey OP, you were released today with performance gains!

Ha, gotchem. The drive by compliment strikes again.
