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.

WinRAR also seems to handle opening a file in an external app without manually extracting much better. I can just double-click a file in an archive and open it in an external app, while with 7-zip it seems to immediately delete the temporary file so the external app ends up trying to open a non-existent file. Rather annoying if you're just trying to quickly check something like the readme.txt in an archive.

>while with 7-zip it seems to immediately delete the temporary file so the external app ends up trying to open a non-existent file.

No, 7-zip only deletes the file after you close its window, so as long as you don't close 7-zip any apps should be able to open those files. Winrar doesn't delete on close, but that has its own problems, namely that you accumulate a bunch of extracted files in your %TEMP% directory, and have to run disk cleanup to delete them.

I just tried it with 7-zip 19.0, and double-clicking a video file in a 7z archive, and VLC could not open the extracted file because it didn't exist.

E: Tried again with procmon monitoring 7-zip, and after it completed writing the file it deleted it.

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.

what is NSIS?

Nullsoft Scriptable Install System, a byproduct of Winamp that is ubiquitous in lightweight software installers for Windows.

Why doesn't Windows ship with an unarchiving utility?

It does, but it's annoying because it treats things as folders, which I suppose is nice if you just want to look inside the zip, but a pain if you just want to extract something in a normal way like you'd do with any other unzipping utility.

Windows has shipped with "ZIP folders" and the ability to create and extract ZIP files since the late 90s/early 2000s I believe (not sure exactly what version.) As of the latest versions of Windows 11, Windows ships with libarchive-based archive extraction, which should let you extract many archives natively (including 7-zip and RAR) via the UI as well as the CLI (via BSD TAR, which also ships with Windows these days…

ZIP Folders was developed by Dave Plummer from Microsoft (who runs the Dave's Garage YouTube channel). It was made in his spare time, then was licensed to Microsoft afterwards.

I'm not sure I'd tell people I did that if it were me.

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. [1]: https://github.com/mcmilk/7-Zip-zstd

Perhaps a tangent, but until now, I've only seen or used "codec" in the audio/video sense. While somehow awkward, it seems this would also be correct, since it also compresses and decompresses. Video codec but archive format.

Sometimes you see a word used a new way and wonder if you've just been wrong all these years.

I think those first appeared in some form in XP. I don't recall 2000 having support for it integrated into explorer.

They were introduced in the Microsoft Plus package for Windows 98, then finally integrated into Windows ME. Windows ME was released after Windows 2000, so the feature didn't appear there. But it did appear in XP. You could actually install the Windows ME version of the shell extension on 2000.
