When you upload files having size more than 100 MB, better go for chunked file uploads. jQuery-File-Upload supports that.

It splits files into smaller fragments with predefined chunk size and upload them one by one. Another advantage is that you can resume file uploads. No need to upload entire file again, if the upload is interrupted. Also it can overcome your upload_max_filesize and post_max_size issue.
