help: how to Resume download from a hotspot file?

I have Mikrotik 3.22 with Hotspot accounts. In the satus page I put link to files that I put in the hotspot folder for the user to download but the problem that when I use Internet download manager to download the files but there is no resume capability.

How I can make the file download with resume capability?

For download resuming to work the client has to request an HTTP range, and the server has to support that option. If the client you’re using (presumably a browser?) does support that capability and downloads won’t resumt the Hotspot HTTP server most likely doesn’t have that ability. Confirm with support but I don’t think you can have resuming downloads.
