Copying and downloading files delayed process.  

I'm having a couple of issues on my Windows 10.

First, if I download a relatively huge file (50mb upwards) the last byte gets stuck. Meaning the download indicator is already between 99-100% but its not completing the process immediately. I'll have to wait 15-30 seconds for it to complete. Same thing if I transfer the file to another folder.

I'm thinking its a scanner issue, although I'm only using the default Windows Defender and non other. And that its not a browser issue since I'm experiencing the same delayed process on File Explorer (copying and pasting huge files).

Could be a variety of things: examples:
a. copying from a temporary buffer to the chosen location (if applicable)
(You could check disk activity using task manager)
b. Smartscreen check: e.g.
Enable or Disable SmartScreen Filter for Microsoft Edge in Windows 10 | Tutorials
Change Windows SmartScreen Settings in Windows 10 | Tutorials
c. AV scan as you suggest

If you capture your PC's activity at the end of the download you may well learn more.


This does however suggest it's more a matter of data being written from RAM (guess).

How much free space do you have on C: ?
Does your RAM get fully used during these events? (Task Manager).

Could this then be a paging issue?

Try capturing screenshots of your task manager towards the end of the copy process and during the delay period.

My SmartScreen settings are set to Warn.

I have about 13.2 GB of space left on C.

I'll check RAM the next time.

Will do take screenshot next time.

Thanks!
