How to view an interrupted video download in Telegram? (Windows PC)

Sometimes,, for some reason I dont understand, in a channel or a group, a video cannot be viewed in the desktop application itself, and I have to download the whole thing, but I dont want to because its huge size and I have limited bandwidth, and I actually just want to only get an idea of it…
So what I do is I disable my internet connection when the download is like only 5% in.. I can see the file in the download folder however I cannot play it..
Is there anyway to solve this irritating problem?
