    New test with Fp8sk29, still warnings while compiling but this time no errors with de/compression.

    Tried default compression ( -4 ? ) and -7, then decompressed and MD5 and CRC32 ok with same files (excel97 and some jpg/gif/png).

    x32 not tested, only x64.

    https://ufile.io/wgvxcfyj only x64

    Same g++ settings and same intel 3770k.

    -------- removed x32 exe from zip

    C:\Users\User\Desktop
    So I need normal command line for PAQ AND FP8SK, at least two file on the path desktop i wrote, I'm on Windows 7 Italy,


    basically in fp8sk30 you used more ram for PAQ and slower speed than fp8sk29
    so for options I need the one you used to benchmark fp8sk30, improved jpeg recompression, not the normal which you optimized the speed
    600 mb ram, 26 seconds for 1,5-2 mb and 2 kb more size than previous but much faster.

    In command line I just type fp8sk30 -8 inputfile
    This is the trade off between speed and compression ratio... You can look at the source code and compare between fp8sk29 and fp8sk30...

    On windows tmpfile() is trying to create a temporary file in the root folder, where normal users have no write access to.
    @danieldeak70, I suppose if you run fp8sk in an elevated command prompt the issue will be resolved.
