Subject: Re: SFTP file transfer for large files using flex

as maybe all know Flash supports only a file size of 100MB.

from the docs:

FileReference -> upload()

> Although Flash Player has no restriction on the size of files you can upload or download,
the player officially supports uploads or downloads of up to 100 MB.

I experienced that an upload / download of a larger file via Flash (FileReference) is possible.

I agree with Avinash! I think this is a good place to discuss this topic (and not the stack
overflow forum). Because this mailing list is the place where we can improve the Flex SDK
/ Flash.

Correct me if I am wrong, but an upload of large files (2 GB or more) is currently not possible
in Flash. And maybe we can check if it is possible to enable a larger file upload / download
via Flex / Flash. This feature is very useful for Enterprise RIA's. I have already developed
such an app and have the same problem.
