Hi Manas,
Thanks for your post. Based on my research, when your downloaded files keep missing, you should pay attention to the following situations:
- If the downloaded files are blocked and removed by Windows Security or third-party anti-virus software
- If you have hidden the downloaded files
- If your computer is attacked by a virus or malware
- If you have deleted the downloaded files by mistake
- If you have run command chkdsk before, it will empty the downloads folder.
To verify the detailed information for the narrow down ways, please see:Files in the Downloads Folder Keep Disappearing! Fix It Now - MiniTool

Thoroughly research any product advertised on the site before you decide to download and install it. Hope this helps.
