Large file uploader

Question

I made a basic upload script by using the w3schools tutorial (here) and I was basically wondering if there was anyway to increase the upload size to above 5Gb. I tried changing the script to upload large video files but it errors telling me that the file is too big. Would anyone be able to help me with the issue that I am having

To try the uploader for yourselves (uploader), it accepts .mov formats, but like I say my error lies within the upload file size.

Answer 1

As others mentioned in the comments you can 'chunk' the file into slices, and upload them piece-by-piece. The server will merge the files after all slices were uploaded. A working demo for this is http://dnduploader.filkor.org.
You can learn from it's source code, what you can find on Github (see the FAQ section on the page).

In general, it's not an easy task to create such an uploader, but from it you can learn some novel ideas about the current 'trends' of file uploading..

Answer 2

As mentioned by Critical Point, you will most likely need to chunk the upload.

There are a number of other additional factors to be aware of - for example error recovery and connection interruption.

It may not be suitable for your uses, but in the past I have had success using a commercial component:

http://www.aurigma.com/UploadSuite/

There is a fairly steep entry price, but provided are multi-platform components for both client and server side. In terms of comparison to building and troubleshooting a home-made solution, Aurigma provides great ROI.
