7-Zip 15.05 is still useful today, because it was the last version to include built-in support for decompiling NSIS installer scripts. The feature was removed due to security concerns.
I wish 7-zip would support .tar.gz the way WinRAR does.
WinRAR allows you to browse a .tar.gz without extracting it, 7-zip extracts the .tar to a temp file. It makes working with large .tar.gz files impossible.
(Yes I know that because of how .tar works WinRAR must decompresses it to build the files list. But it beats having to write a 1TB .tar to disk just to see the file listing.
I wish either RAR or 7-Zip would finally implement a memory-hard KDF for encrypted archives.
Lately I use zstd + tar for making archives that preserve file metadata.
Why doesn't Windows ship with an unarchiving utility?
For those who are unaware, there is another project [1] that tracks upstream which adds support for various codecs like Zstandard. Many folks (such as myself) opt to install their releases instead.
