Sounds like you just need /tool fetch.

The blacklist script is a thorough example: https://github.com/kd7lxl/blacklist-service/blob/master/block-address.rsc

I am trying to achieve something using RouterOS scripting, and I'm hoping that here I might find the appropriate expertise.

From a script running in a Mikrotik router I wish to pull in a copy of a file from an attached Windows computer. The computer is on the same subnet as the router.

By way of illustration:

     A file called test.xxx exists on a Windows computer in the folder c:\aaa\

     I want a copy of this file to appear in the attached router /file list. This copy "event" could be either a push from the computer, or a pull from the router.

When using Winbox, this function is achieved easily using "drag and drop", but I need to automate the function.

Thanks.
