Invalid arguments

When I try to load a 2.2GB .zip file, jszip throws an error. Other .zip files work just fine.

I've tried other .zip files, up to 4GB, that work without problems, so I don't think the size is an issue. The file has been .zipped on Mac OS, I've tried unzipping it an re-zipping it on a Linux machine but it didn't help, I get the same error.

In chrome, the whole page just crashes, in Firefox it catches the error nicely:

TypeError: invalid arguments

I get the same result without using JSZip : a <input type="file">, a FileReader and a new Uint8Array(e.target.result).

In Firefox, a 1.8GB zip file works (I can get it and parse it with JSZip). With a 2.6GB file, I get a ArrayBuffer { byteLength: -1511021340 } in e.target.result and an exception when I create the Uint8Array. It looks like the byte length overflows and Uint8Array isn't happy with negative sizes.

In Chrome, a 1.8GB file crashes the tab, a 2.6GB triggers an error (reader.onerror) : a "NotReadableError".

I would say that 2GB is too much for a browser. How did you load a 4GB file in a browser ?

Hmm it seems you're right. I ran a few more tests with dummy files. Just created dummy files in ubuntu and compressed them with 0 compression. A 1GB file crashes chrome, works in FF. A 2GB file fails in FF but doesn't crash it.

I would swear I had a ~4GB file working at some point.. I don't have that specific file anymore though.
