    EXE being compiled in 2010 looks suspicious, but I guess its ok?

    1/69 ratio...
    "Suspicious.low.ml.score" which means Trapmine's Machine Learning detector didn't quite like it but it won't say why. 'Because'

    Basically a false positive.

    -------------------------------

    BTW: Does anyone knows what kind of a compressor is this? Could be a form of this algorithm? Or this?

    My quick test on enwik8:

    Code:
    Total input size: 100000000 bytes
    Total output size: 28054812 bytes
    it tooks 20.44 seconds. Great!

    Decompression verified OK - 100% match.

    What does it mean "switch" here? At least in CMD there isn´t any examples of use nor description...

    So it seems: https://patents.google.com/patent/US6199064B1/en
    But there were quite a few implementations despite that.
    Also I don't think that you can patent reading one buffer and writing to many.
