Could be possible to add support for LZIP?

Total7Zip can use external plugins for 7Zip. And there is (my) 7zip plugin Lzip7z that can open and create lzip files. Just copy plugin files into Codecs and 64\Codecs subfolders and Total7Zip will be able to work with lzip.

Also you may be interested in 7zip plugins eDecoder, Asar7z and WinCryptHashers.

wow tanks a lot
maybe this has been discussed but any thoughts about zstd fork of 7-zip
https://github.com/mcmilk/7-Zip-zstd/releases

ps Dec what's the license to your codecs is the source code available?
could you fork/update the codecs from
https://github.com/mcmilk/7-Zip-zstd
not to depend on a modified 7z.dll as your codecs work great out of the box while the above need a replaced 7z.dll which is a bad idea specially as 7-zip has been updated and that project seems staled

[Dec]

Free but with close sources.

could you fork/update the codecs from https://github.com/mcmilk/7-Zip-zstd

I am not C++ developer.

not to depend on a modified 7z.dll

zstd and other codecs are NOT depend on a modified 7z.dll. They work with original 7z.dll without any problem. And they can be used with Total7Zip also.

[iana]

OK tanks
my mistake I just installed your formats and put the zstd fork dll's in the formats instead of the codecs directory
but the codecs alone don't have support for zstd files the modified 7z.dll is needed for "full" support using the codecs only allows for the zstd to be used inside 7z archives

edit
I think Igor did some changes in 7-zip 18 as the zstd codecs don''t appear in the 7-zip GUI or it could just be me

[Dec]

I think Igor did some changes

7Zip GUI does not provide a simple way to select any additional CODEC for 7z archive. The only variant is write 0=ZSTD in Parameters input box. But 7Zip GUI allows you to select additional FORMAT implemented in external dlls.

[iana]

I can't see the additional codecs but I remember testing these dll's a year ago and while I couldn't create a zstd archive I could select zstd as the compression method from the 7-zip Explorer GUI (replacing the 7z.dll allows me to see/use zstd in a 7z archive or create a zstd file)
running

Code: Select all

7z i

I do see that the dll's are loaded but no entry in 7z-FM
I'm not that good with long command line parameters
I wanted to test/compare zstd vs lzo vs lzma but I always endup using lzma
I find it strange that nobody's written a lzo plugin for TC (there was an unpacker only released years ago https://totalcmd.net/plugring/lzop.html )

Again. Original 7Zip GUI does not provide... GUI of 7Zip ZSTD provide...

I do see that the dll's are loaded

Can Total7zip plugin (0856) create multiple volume archives, if it can then how?
Its Option for the purpose does not work.

[trevor12]

I found on net some benchmarks and it is clear that mainstream archiver (rar, 7zip, zip) are not best (speed, compress ration)

http://www.maximumcompression.com/data/summary_mf2.php

http://www.squeezechart.com/

click on header on

download benchmark as OpenDocument spreadsheet download benchmark as Excel spreadsheet

I recommend especially to see speed of density and efficiency of nanozip and freearc

win32 version has gui, win64 version only command line

freearc

also for me is interesting this configuration for make 7zip archive:

[Orochi]

I do see that the dll's are loaded but no entry in 7z-FM

My problem is that I see double of every codec in the 7zip FM.
I am using latest 7zip 18.01 portable. I copied x32 and x64 codecs to the appropriate directories. 7z-x32.dll and 7z-x64.dll were copied as well the formats folders. Without them, I don't see the codecs in the 7zip FM.

PS: Don't have such problem with Dec's dlls.

[iana]

I came across an AppImage file that 7z-FM opens fine but TC with Total7zip does not open it
according to 7z-FM it's a SquashFS file

I got the file from xnview it's an appimage of xnview-mp for Linux
https://newsgroup.xnview.com/viewtopic.php?f=82&t=37173
my question does anybody know how to add the newer formats supported by 7zip to the total7zip plugin ?
I use the latest 7z.dll with total7zip the same one as 7z-FM so it's not a dll mismatch issue

ps
a bit off topic but to avoid multiple posting

it should but it does not it's a bug in the plugin but the author seams to have abandoned it, you don't really need it as Total Commander can create split files the so called multivolume 7z is not a real multivolume
you can create a 7z file then use TC's build in split function,
select the file then from the menu do
File-> Split Files ...
and you'll get .001 .002 ... files

yeah well no not really there are other packers out there for instance I've found uharc to be among the best compressors out there
ftp://ftp.sac.sk/pub/sac/pack/uharc06b.zip
but it's abandoned it doesn't have a native 64bit port and it's slow as hell
freearc looks good but if I'm not mistaken it's written in Haskell amd C++ and it's a lot lot slower then 7z which is a combination of assembler C and C++ both WinRar and 7-zip outperform it in speed and 7zip can outperform it in compression

[Octopuss]

Can anyone update the plugin with current 7zip files please?

[Gral]

Everyone can

[Horst.Epp]

Can anyone update the plugin with current 7zip files please?

Download the current 7z files (18.05) and overwrite the files in the plugin.

[MVV]

Or just write path to installed 7-Zip into plugin xml config and delete its own 7-Zip folder.
