Precomp and SREP
i have heard a lot that precomp and srep help in compressing files to a great deal...
but till now i have not been able to do it ... i had seen a release..that had the final files packed in .arc...when i start extracting..a .pcf file is extracted that is of a very huge size...then a rar file finally comes out which as a size smaller than the .pcf file...?? does anyone know how do such stuff ?? I tried to compress the final extracted files directly with free arc..but i don't get such a compression ratio.. Please Help ME !! |

Compress the game files with freearc with -m0 command (no compression). the resultant file is (eg. data.arc) is processed through precomp. then work srep on that file ( data.pcf). then finally compress that srep file (data.pcf.srep) with freearc again with maximum compression. data.arc>data.pcf>data.pcf.srep>data.cab you can try this but every game has different compression method for minimum size. Good luck |

best method is to try different parameters for different files. look at the following linkhttp://freearc.org/HFCB.aspx u can see the difference between compression ratio with slight change in parameters with freearc. Try different parameters with precomp and srep as well to find out well suited compressions. I hope it will help. you can use Kurutucu Compressor as well if you want. |

@DazzleR
That .pcf file (PCF = PreCompressedFile) contains more decompressed data than the original file.. |

1. download precomp
2. either drag your data.arc file on the precomp.exe or open notepad and type the following command precomp.exe -odata.pcf data1.arc pause and save the notepad as.bat file place this .bat file in same folder along with data.arc and precomp.exe run the .bat file and you are done. precomp.exe -odata.pcf data1.arc ---------------in that command line -odata.pcf is the name of output file (u can change it from data.pcf to anything as u wish with .pcf extension) data.arc is the file for compression. for more information about different options in precomp for better compression look at following link http://schnaader.info/precomp.php |

i thought u want a small size by using precomp but if u want a large .pcf file using following commands precomp -intense -v -c- -oData1 Data1.arc -c- means zero compression for output file (better srep results) -v means debug mode (if something goes wrong you can see problematic position and start precomping once again but with -i######### parameter; ######### means problematic position) |
