List of formats planning to add support in NanaZip 3.x

[MouriNaruto]

Here are some formats planning to add support in NanaZip 3.x development stage. I think users will be happy if I can implement all of these. But I also need some help.

Note: You can give your suggestions about the new formats want to be added in NanaZip as comments for this issue. I will read that without replying in most cases.

warc (ISO 28500:2017, wikipedia) is mentioned in tc4. It's also supported by libarchive (bsdtar), another "decompress anything" tool.

tc4 mentions a bunch of e-mail and usenet formats. these tend to be not too complex, but really ancient and hard to hunt down. having someone do it once and for all is of course great.

Now NanaZip can't unpack NSIS2020+ Package such as Unity Editor 2020+ Installer.

Unpacking&packing PRI is needed.

Unpack .unitypackage, NanaZip can't parse file path&name in zip

Unpack .resS，Implementation Reference：Perfare/AssetStudio

Apple seems to have cooked up a new format called aar and made it the default output for their OS right-click. https://eclecticlight.co/2022/05/10/inside-apple-archive-more-than-a-compression-format/

Thing is, nobody knows what's in the format beyond what Apple APIs to call. So a very good-to-support format, but impossible to support for now.

[Neustradamus]

To follow

[MxMaster3]

Any chance for this one to be supported?

[Artoria2e5]

hmm, do people really use paq outside of compression challenges? It's even more niche than ZPAQ...

I've seen it do some extreme compression on these old psx iso roms -

[Stanzilla]

Asar would be nice, indeed

[mbc07]

I would like to request support for ZArchive (.ZAR/.WUA), here's a reference implementation. AFAICT it's just ZStd with a different container format...

[modz2014]

With plugin in support i suggest the developer to release the source code these files I have read on some forums that contain malware

[Artoria2e5]

The thing about "some forums" is that you can say whatever you want on them. I am all for making things open-source, but developers are free to do whatever they want given the plugin API license, and being a clueless panicking person who hasn't heard of VirusTotal is surely not a very persuasive way to encourage open-sourcing.

[modz2014]

Certainly, here's a more professional way to express your thoughts

@Artoria2e5, it's within their discretion to make their choices. However, I haven't personally used or tested their services; my knowledge is based solely on feedback from other users and sources.

[JacobCarrell]

Please don't add "advanced" filesystems (anything besides UDF/ISO9660/Juliet/Other-Optical-Formats, (ex)Fat(32), Maybe the ext file systems). Resist feature creep, stick to the core value of "archive opening utility"
