It's 2023 year of our lord and I still can't upload a file larger than 4GB? #52498

Is there an existing issue for this?

Is your feature request related to a problem? Please describe the problem.

I am trying to upload a file larger than 4GB on a Windows server, but I can't - compare that to Google Drive which has a max upload size of 5120GB

Describe the solution you'd like

I should be able to upload any size file that will fit on my server.

Additional context

No response

Hello, can you show a snippet of code?

catmanjan commented 11 months ago

@danmoseley not really - but there is this doco https://learn.microsoft.com/en-us/previous-versions/iis/settings-schema/ms689462(v=vs.90)?redirectedfrom=MSDN

Ok putting in area-runtime and someone with context can give guidance.

Are there any particular errors you get when uploading a file larger than 4GB?

The MaxRequestBodySize feature uses a long so, in theory, you should be able to set a limit larger than 4GB.

Perhaps this could be related? #2711

@david-acker not really - it just doesn't respond

I think this is a long standing historical issue with IIS https://stackoverflow.com/questions/699488/file-upload-of-more-than-4gb

ASP.NET Core has no control over IIS settings. It looks like IIS uses a uint for its setting which is equivalent to 4GB. IIS feature feedback can be posted at https://social.msdn.microsoft.com/Forums/en-US/home?forum=iisfeaturefeedback.

If you want to upload more than 4GB you can use Kestrel instead which uses a .NET long so will support a much larger file size. You can see https://learn.microsoft.com/aspnet/core/mvc/models/file-uploads?view=aspnetcore-8.0#server-and-app-configuration for details on configuring the limits in ASP.NET Core.

As a side note, the stackoverflow post you linked has multiple people mentioning that uploading large files would probably be better if you chunked it up so that if the connection goes down in the middle of uploading it can resume where it left off instead of starting over from the beginning.
