This came to my surprise when I saw YouTube allows you to upload file of size of up to 20GB rather than 2Gb limit which I thought before. Read more at their support page.This large size file upload is possible using the Advance Uploader of YouTube which supports :
- Resumable uploading : Useful when you are slow network connection or when connection breaks. YouTube uploader will start from where it left saving your bandwidth.
- Needs Java 1.5 or more.
I am not sure if this is enabled for all the accounts because till date I have heard this is only available for partners account. To upload upto 20Gb file try this url and make sure you have the java client installed.
