That doesn't work...

Can't we do it server side itself(.aspx.cs file)

I have not worked with the fileupload control myself yet, but I doubt you can do what you wish serverside, because for it to be done serverside, you need to have the file uploaded.

However, there is a setting for the httpRuntime called maxRequestLength in which you can set the max size of the request, and thus the file. However, again - I've not worked with this, so how it works excatly I can't tell you, but I recommend you checking out the documentation: http://msdn2.microsoft.com/en-us/library/system.web.ui.webcontrols.fileupload.aspx for the fileupload.

For a check as you request, I'd personally do it client side; meaning javascript - although thinking of uploading an up to 200GB file via fileupload seems .... excessive and I'm not even sure you can get that done using that technique and I'd advice you to use FTP to upload the file(s) if they are large.

I'd still say 200MB is a large size to upload via HTTP fileupload, and would still advice you to look into making it into an FTP upload :)
I've personally had problems with server time-outs and all sorts of problems, when clients were uploading 40MB files even on "fast-ish" connections.
Just my personal experience talking.
