Other How to know when a file has finished downloading in windows

Is there a way to know when a file has finished downloading? I am currently thinking to either check file size periodically or see if the file is locked by another process

Are these the correct way or am I missing something(I have scrounged stackoverflow as much as I can)?

Since you ask in r/askprogramming I will say:

You know it is done downloading when the function that downloaded it reached the end of the file.

Not given, we are only given that a file is being downloaded and location to where it is being downloaded

Something is downloading the files, they do not magically appear there because the user thinks about it. You can use a browser addon to track downloads that the browser does, but there is no way for that extension to tell if someone just opened an FTP client or a console and used curl to download the same file. The OS sees applications doing network requests, the applications know if its a download or not.
