    SRep made 6gb archive into 3gb

    well just posting a fun little benchmark i did

    its the iso file for an x-file game

    original size = 7.88GB (8.468.776.960 bytes)
    7-zip lzma 192mb/273 = 6,01 GB (6.460.937.110 bytes)
    srep64 = 4.19GB (4.504.471.592 bytes)
    srep64 v1.00 -> 7-zip lzma 64mb/273 = 3,31 GB (3.562.574.200 bytes)

    pretty amazing results from srep64 as preprocesor and/or standalone compression.

    and it shows there is reall life files out there that benefits from huge dictionary size compression.

    i wonder if rzm could get it even more down

    the memory usage doing decompress dropped tremendous.
    72mb for 7-zip adn 18mb for Srep

    its just called X-files

    some more info form the readme.txt

    The X-Files DVD
    Release 2.05/US


    The requirements its pentium 11 233mhz or higher so its an old game


    but i have more dvd iso game files where rep and Srep gives huge boost in compressions. even when going above 1.5gb dictionary in the old rep utility

    hi all first post but not new, being following you for some time
    SvenBent, what was your command /switch settings?
    X-Files game contains Huge amounts of Multimedia, i remember this one
    Would be interesting to try newer Game but using the same switches

    7-zip (-tzip -mx0) + srep (default) + 7-zip (above settings) - 311 mb

    Hey Bulat, i want to thankyou for FA.Best Compression/speed ratio. I combine it with Precomp, and Well you know that it works beautifully
    I was wondering though how would Srep integrate into my workflow? and how does the command line work?
    If you could give me an example i would be Most grateful
    I tried to use it and failed
    I usually use precomp then use FA to compress, but ive been told that using Srep can give better results. But this person wouldn't share there knowledge I hope you can assist me in my endeavor to learn
    Yours Respectfully Omnikam

    FA = FreeArc, a stunning compression tool made by Bulat Ziganshin (member of this forum).

    just drop your files into Srep or Precomp .then Cmd will open and it will compress files.
