Question

I’ve tried many tutorials online on how to increase the upload file size for a SharePoint document library with no luck.

Any ideas on how to increase the limit of file upload to a document library?

I’ve tried:

Answer 1

I followed the 1st instruction from the 2nd link you provided:

1. In SharePoint 3.0 Central Administration, Application Management
   tab, and Web application general
   settings configure the Maximum upload
   size to a maximum of 2047 MB.

and it worked fine.

Are you sure that you selected appropriate Web application when changing the maximum upload size?
