Splitting a file before upload?

Question

On a webpage, is it possible to split large files into chunks before the file is uploaded to the server? For example, split a 10MB file into 1MB chunks, and upload one chunk

Answer 1

Do you specifically need it two be in X chunks? Or are you trying to solve the problems cause by uploading large files? (e.g. can't restart an upload on the client side, server side crashes when the entire file is uploaded and held in memory all at once)

Search for streaming upload components. It depends on what technologies you are working with as to which component you will prefer jsp, asp.net, etc.

some try to manage memory on the server,e.g. so the entire huge file isn´t in memory at one time, some try to manage the client side experience.
