As per title. It will save space on the servers and allow the file size limit to be raised. It also will improve download times. You may argue that using .tar.xz will slow down decompression but, there are varying levels of xz compression that can be used. Smaller projects can use less compression and will be decompressed faster. Only the large projects really need higher compression ratios (btw I'm not talking about internal combustion engines).

Support: This would really help because since it has been compressed, the file size will be smaller which means it will not take ages to download on my internet (the worst internet ever). De-compression times won't matter for me because my computer has an Intel i7, with 16 GB of RAM, and my computer is 64-bit.

No support, some computers might not be able to compress the project because some computers upload as .7zip.

No offence/offense, but it sounds like you made up something that's sounds computer-ish.

Computers don't work like that. “Some computers” don't upload as 7zip. Scratch 2.0 file format isn't even 7zip (it's just normal zip). So why do “some computers” not fail to upload Scratch projects?
It isn't Windows (which only supports normal zip by default)/Mac that does the compression work if it is a program that needs something to be compressed. It's the actual program, which in this case is Scratch. Scratch always uploads as normal zip. So, it doesn't matter if it gets changed. Also, there would still be compatibility.

I meant normal .zip. Still, how would computers upload it if they do not support the .tar.xz format?

??? The Online/Offline would have the tar.xz format built in…

I'm not sure if you didn't read my post properly, or if you don't know how computers do stuff. (No offence/offense)

If you don't understand that then I'll simplify it. Scratch would already provide the tools to compress files. Don't say “that would be to hard for the Scratch Team to do”, because programs like 7Zip are basically programs that “already provide the tools to compress files”. Also, I think 7Zip is open source, so if the Scratch Team can't program it, then they could use the code from 7Zip. (7Zip might be not open source though)

That's basically what I said.

Do you mean in .sb2 or .sb3 format or something else?

I'm not sure I understand. Do you not understand the suggestion, or you do understand but want to know if it's in .sb2 or .sb3 format. In that case, both.

No support, tar.xz files do not work on many computers.

How so? Scratch would use its own implementation (probably using a port of 7-zip or similar)

I feel like you're using faulty logic. ALL COMPUTERS ARE TURING COMPLETE AND CAN SOLVE ALL COMPUTATIONAL PROBLEM (in theory).

Why the .tar.xz file format? Never used it, and by your explanation it looks like it's something that would cause a slow down.
No support.

It's not going to make a difference to the average user.

Wherever it seems most practical to the ST. I mean, you wouldn't want to have a new sb2 opened in an older version of scratch and not work.

In fact, for many people who have slower internet, It might even be faster.
