How should TC be able to compress in 7-Zip without a plugin ?

How should TC be able to compress in 7-Zip without a plugin ?

In the same as it handles zip files without a plugin?

TC and Mr. Ghisler have no rights to include 7-zip code in the main program.
Read the EULA and license agreement.

EDIT:
sorry, I remembered it wrongly and take all back. See below for more...

Well, TC already ships a DLL (tc7z.dll or tc7z64.dll) for extraction of 7-zip archives. So what would be the reason that it couldn't ship a DLL that also creates such archives? Many other programs use 7-zip DLLs.

Still, two independent plugins exist - both of which have their own issues* - and the 7-zip program can be used via the context menu (or even the command line), so the need to integrate 7z packing into TC is certainly decreased.

*) The 7-zip plugin uses only two threads for packing which makes it slow and not utilize modern processors.
The Total7zip plugin copies files to %TEMP% before packing when packing directly into a subdirectory within the archive: viewtopic.php?p=425122

This isn't true. 7zip is released under LGPL license (library GPL), so it is allowed to include the library as long as any changes to the library itself are again open source.

The main reason why I don't include 7zip packing are:
1. There are a LOT of options which will overwhelm the casual user. Leaving it a plugin ensures that only experienced users will use it.
2. Keeping the ZIP format as the main format has a lot of benefits, like everyone can unpack ZIP files without third party software, and there are no exotic compression methods the user could choose as with 7ZIP.
3. There are 1000s of more important features to add, and I only have limited time to add them. There is no big gain to add internal 7ZIP support compared to using a plugin.

Christian,

Just FYI, Windows 11 is getting built-in RAR and 7-Zip support.

At the time of this writing, Windows 11 is still at just 23% share, Windows 10 is at 71%.

What's about replacing UC2 with 7zip exe? You even can't use old 16-bit UC2 on any Win64.
Just give the exe path in config to use 7z.exe packer. There should not be difficult.

Then it may be something like this in wincmd.ini:

Code: Select all

ACE=%COMMANDER_PATH%\Ace32.exe -d4096 -m5 -s -c2 -o
ARJ=%COMMANDER_PATH%\Arj.exe -a+ -r+ -y+ -jm0 -jt+ -j$ -jh17000
LHA=%COMMANDER_PATH%\Lha32.exe
RAR="%COMMANDER_PATH%\Rar.exe" -ma4 -m5 -s -t
7z="%COMMANDER_PATH%\7z.exe" -mx9 -mqs -mfb273 -md26

That will be good enough for most purposes.

1. There are a LOT of options which will overwhelm the casual user.

Modern casual users much more overwhelmed with UC2, LHA, ACE or ARJ archivers

how? those packers dont even have a configuration dialog?

Do they need it? AFAIK, you can just write cmdline to use maximum compression for always. The same is for 7zip, you may use best compression with 64 or 128 MB dictionary in most cases (OK, not always, but at least 99%).

[KozakMak]

imho UC2, LHA, ACE or ARJ must be as plugin
7z = by default

Although I would very much wellcome a 7zip support without a plugin, we should respect the statement by Mr. Ghisler. He has other priorities, full stop.
