Limit download with IDM in Mikrotik

For those of you who want to restrict users who use a software download IDM (Internet Download Manager) in Mikrotik. Here's how, For I do not want to bother with what the extension, but can also be configured like this:
* Browse the full bandwidth
* Download any file extension, which is more than 1M, will terlimit so 256kbps
* If the download <1M, will get a full bandwidth
* Watch the video has finished dilimit 128 kbps

I apply this Setiing using RB750G
