FileUpload issue with IE and large files

[thomasp]

I noticed an issue when using FileUpload in advanced mode, specifically uploading files over 4Gb in size on Internet Explorer (tested version 11). Almost immediately after selecting the file the console logs the error "SCRIPT534: Arithmetic result exceeded 32 bits" for fileupload.js and the upload stops. Tested with Firefox and Chrome and both upload larger files (over 4Gb in size) without issue.

Has anyone else encountered this or have any suggestions?

Sounds like a generic IE issue (the core maybe still being 32 bits or something)... Any related hits on the internet in general?

Edit: Yes generic IE issue https://blogs.msdn.microsoft.com/ieinte ... ad-limits/

Thanks for the link and info. From the PF user guide I was under the assumption the advanced uploader used HTML 5 FileAPI which should be supported in IE 10+. Just wondering if anyone else had encountered this but I'll do some more digging on my side and see if I can trace it down a bit better.

So the question is if slicing is supported or not?

Yes, I was wondering if anyone had managed to get it working but looking at the code a bit more I can see that it isn't setup for it.
