Would be great if the file manager could support Uha i have loads of files in that format and it makes sense to open it in the best file manager. plus its a better format than zip and rar as it compresses smaller.
I couldn’t find anything backing that up, outside of specific niches. Consensus seems to be it’s an old format that’s useful for smaller game repacks but not the right format for general use.
Its an old format that compresses better in most cases zip and 7zip. I tested the compression format with different files and UHA came back slightly smaller. It was an idea to add more compression formats to make people want to use directory opus over a dedicated compression program.
It’s also abandoned and seems to have no source code or library available, which is why nothing supports it.
