    New 7zip SFXs optimization !!!

    Sorry if I have grammatical errors I speak Spanish. :=)


    This is the last optimization of the 7zip SFXs by me.
    --------------------------------------------------------------------------------------------------
    --------------------------------------------------------------------------------------------------

    In the folder ONLY LZMA you can found a SFXs optimized to unpack the
    Files .7z packed with the method LZMA only this

    The file lzmsmall.sfx is bery small and don't have icons

    Only >>>34,0 KB (34.816 bytes)<<<

    The file LZMA.sfx is small and have icon

    Only >>>35,1 KB (36.043 bytes)<<<

    The script do.bat is to make a SelfExtract from a file .7z saved in the same folder
    You can copy a .7z to the folder LZMA and execute the file do.bat

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

    If you don't Know the packed method of a .7z you can use the self extractors saved in the folder
    "All methods"

    The file 7z.sfx is small and don't have icons :
    Size >> 39,5 KB (40.450 bytes)

    The file (Icon)7z.sfx.exe have icons :

    Size >> 41,6 KB (42.699 bytes)

    The script do.bat is to make a SelfExtract from a file .7z saved in the same folder
    You can copy a .7z to the folder "All methods" and execute the file do.bat
    --------------------------------------------------------------------------------------------------
    --------------------------------------------------------------------------------------------------

    You can use this SelF-Extractors with you preffer program like PeaZip ,7zip ...
    Ej Copy the file lzmsall.sfx to the Program Folder\7z\
    and put the name 7z.sfx or 7zCon.sfx.

    This files are ready to download form the peazip add-ons page in Sourceforge.net

    --------------------------------------------------------------------------------------------------
    --------------------------------------------------------------------------------------------------
    In a few day I go to publish a SelF-Extractor with only the method PPMd

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

    That looks cool
    By using upx --brute it can be easily brought down to 18 944 bytes; after removing the icon and upx --brute it became 15 360 bytes.
