Z-Standard (zstd) support

[xkip]

Hello, few years ago we got built-in 7zip support for unpack and search. I believe it is a time to bring zstd build-in support into Total Commander. Would it be possible to implement that? It is now industry proven and often superior algorithms, supported even as a browser content encoding.

You mean packing? Unpacking seems supported already.

New functions and fixes in Total Commander 11.00:
...

File operations:
...
- Unpack ZIP files with ZSTD (by Facebook) compression
- Unpack .zst (ZSTD) and .br (BROTLI) files

Total Commander only supports ZSTD in ZIP files and .ZST files, not in 7Z files. Why? The standard 7z.dll does not support it. You can replace tc7z.dll and/or tc7z64.dll with one which supports it if you need it, e.g. from here:
https://github.com/mcmilk/7-Zip-zstd
You need to rename the 32-bit 7z.dll to tc7z.dll, and/or the 64-bit 7z.dll to tc7z64.dll.

the 64-bit 7z.dll to tc7z.dll.

correction: to tc7z64.dll

Sorry for the typo, I have corrected it. It was correct in the previous sentence.
