How to detect new file download in Windows OS?

Question

I am making a program that scans any new file downloaded into the system. Currently, I have used a file watcher that monitors a directory. Whenever a file is downloaded from chrome then the following happens :

For example: Let's say a pdf file is being downloaded.

• .tmp file created first

• .tmp file is renamed to .crdownload

• .crdownload is modified multiple times

• .crdownload file is renamed to .pdf

• .pdf file is modified multiple times.

The problem is when can I say a file is downloaded because it is modified multiple times after renaming from .crdownload to .pdf file.

Is there any way to detect a new file downloaded into a system?

Thanks for the help.

Platform: Windows

Language: C, C++

from what I understood you want it to get the file final extension, for this you can check the file extension evrytime to see if it is a .tmp or .crdownload; but not check for if it is a new file. Sorry for my bad English, Hope this helps.
