I mean , I use linux but I can use wine to run the content inside , so in some sense "every content" is cross platform. I think it ultimately adds to better performance specifically for executable torrents in the long run over things like zip.

Traditional file compression doesn't work that well as compared to upx. Upx supports as much as 500 mb/s on any reasonable device (this is very comparable to https://github.com/mhx/dwarfs) , which is honestly insane.

What advantage does it have over existing methods? It’s great that it’s cross-platform, but so are zip files. And the content inside isn’t cross-platform, so I don’t think that ultimately adds anything.

It states that the more people use and report upx as non antivirus to windows , the better detection rate occurs. This software is open source y'all. Not sure why you all have got your pitchforks
