One more thing, when I try to unpack the archive, I get "Unsupported compression method srep:m3f:a1:l512"

This is my .bat file

Code:

-msrep:m3f:a1:l512+delta+xz

And arc.ini

Code:

[External compressor:srep]

;options  = l%d (minimal match length, default=512)

header = 0

packcmd   = srep64 {options} $$arcdatafile$$.tmp $$arcpackedfile$$.tmp

unpackcmd = srep64 -d $$arcpackedfile$$.tmp $$arcdatafile$$.tmp



[External compressor:xz]

header = 0

packcmd   = xz a -txz -an -mcrc=0 -m1=lzma2:d200m:fb=273:mf=bt4:mc=1000000 -mmt=4 -mx9 -si -so <stdin> <stdout>

unpackcmd = dec x -txz -an -y -si -so <stdin> <stdout>

I copied dec.exe (for unpacking) to my script folder and defined it inside the script

Code:

#define XZ



#ifdef XZ

Source: ISDone\dec.exe; DestDir: {tmp}; Flags: dontcopy

#endif



#ifdef XZ

    ExtractTemporaryFile('dec.exe');

#endif

Thanks in advance.

{-option } u forgot - this will make the whole srep options don't work
packcmd = srep {-option } $$arcdatafile$$.tmp $$arcpackedfile$$.tmp

try this is comprass 60mb to 7.5mb ----> 30gb to 7gb or 15gb

Download This arc.ini And Replace In Masked Compression

ISDone.dll error

Everything works fine but when i open the installer it shows a error with tittle "ISDone.dll" and says 'Failed to open the archive in the module IS7zipExtract!'.
Please Help!!:confused:

IS7zipExtract work only 7zip not working to Arc or masked

I believe some of the tools included in this have been surpassed by newer iteration/implementations.

Would the author be so kind as to accommodate the changes?

IS7ZIPEXTRACT function isn't needed at all since 7zip is merely an internal compressor used by arc

Arc exe has it in ini so long that is true that function is useless

any idea why .minizip files are not compressing at all i tried almost all methods like ultral1,ultral2,ultral3 and medium l2 and none of them compresses the file at all :/
i am using masked data 2.5.1 and yes i have also tried 2.5 but still the same problem

High entropy of some files negate their ability to be compressed this is why bik and other video files are incompressible , it's because they are already compressed once . You need to extract them first

but if i extract them then is it possible to put it back to .minizip format again ?

or you could use pzlib on them and save time ? minizip files are very much recompressible with pzlib.

in masked data one of the methods has pzlib in it but oh well i will try just pzlib but is there like a pzlib compressor like masked data ? cause i really don't know how to use pzlib :p

so first i used only pzlib and it went from 5gb to 9gb then i used pzlib+srep+lzma that gave me this result

^So what's wrong with it ? PZLIB inflates your zlib/deflate input so you get larger output, using a stronger compression on that output makes it smaller.

as you can see in the picture the ratio was 85.84% i wanted it to go lower than that :/

pzlib makes file bigger, because it find precompressed streams and extract them. thus allowing for better compression to be implemented
