Hi,
Is there any option, do not allow downloading of big file of certain size …
For Eg: when somebody trying to download a file of 12MB, they want to get alert message like file is too big to download.
thanks in advance,

You can’t tell ahead of time how big a file is going to be, so you can’t throw up a warning at the beginning of the download.
You can kill any connection that has transferred more than a specific number of bytes - but that is extremely crud and won’t just affect downloads. It’ll also affect streaming, RDP like protocols, VPNs, and any other connection that transfers a large number of bytes.
well, almost every server reports file size before downloading - you can see that in your download manager 
the other question, you can’t use this data even in RouterOS WebProxy rules =)
Some HTTP servers will announce file size, yes. Not all though. And there’s many other protocols. Even HTTPS would thwart this since the header is encrypted.
It’s to be used with hotspot with radius authentication.
I am not so familiar with web proxy.
My customer has some privilege users called called ‘Free users’, liberal to use without time limit but should be warned without interrupting the session when downloading bigger size files
what about using burst? at start you get faster speed, then you get slower speed. good for small files like when browsing.
But I hope web proxy will do it for you, right ?
