Hello Igor, thank you for working on Zstandard inclusion into 7-Zip. To the Zstandard ZIP/ZIPX thing: In summer 2020 I wrote a E-Mail to WinZIP and PKWARE because of the different IDs. The answer of Winzip was: Hi Mr. Reichardt, Per our Development Team: zstd is only implemented in our Zipx format which created and that we define. PKware added it to the zip format. Therefore there is no conflict as ID=20 will only occur in Zip files and ID=93 will only occur in zipx files. WinZip will not create...

For zstd squashfs you need the full installation via 7z19.00-zstd-x64.exe ... the codecs of Codecs.7z will add zstd only to .7z archiv files.

The file is compressed with zstd ... you may try 7-Zip ZS for it: 7-Zip 19.00 ZS v1.4.5 R2 (x86) : Copyright (c) 1999-2019 Igor Pavlov, 2016-2020 Tino Reichardt : 2020-06-03 Scanning the drive for archives: 1 file, 0 bytes Testing archive: squashfs.img Path = squashfs.img Type = SquashFS Physical Size = 1668644864 Headers Size = 19208 File System = SquashFS 4.0 Method = ZSTD Cluster Size = 1048576 Big-endian = - Created = 2020-01-24 21:16:01 Characteristics = DUPLICATES_REMOVED EXPORTABLE 0x400 Code...

Please take a look into the Commit Message ... it's the benchmark numbers which makes zstd popular, not some buzz marketing ;-)

I just added this feature to 7-Zip ZS

I just created an commit for 7-Zip ZS, which will add LZ4 and Zstandard to the next release... you can test it with some pre-build binaries ;) Some first testing seems to be okay...

Hello Igor, could you also provide the source code for the last versions - it would be nice ? Also, if you website isn't reachable from some countries because if the cloudflare IPs - I could give you the space here in germany. With best regards, Tino
