Hi,

Unfortunately there is no Java library that can extract rar 5 archives.

See here : https://stackoverflow.com/questions/56700651/is-there-a-solution-to-read-the-rar-files-of-version-5-using-junrar-library

And the rar library I use in Komga : junrar/junrar#23

One solution would be to use an external tool to perform the extract, but it would be platform specific, so difficult to maintain, while the current library is native Java and portable.

Rar 5 should be fairly uncommon, given the lack of support for the format in general.

In case there is a native Java library implementing it, then I would add it of course.

What about https://formats.kaitai.io/rar/index.html? It seems to me they can at least read rar v5. But have not tried it.

I have seen this one indeed, but Kaitai is only describing how a file is built/formed, it doesn't have the algorithm to uncompress rar5 files.

I see. When I upload a rar v5 to their IDE https://ide.kaitai.io/ it crashes when parsing the archive. Looks like its not stable now.
