I have been downloading files in four concurrent windows. All of them are stopped at 99%. Why is it stopped?

After complete downloading, the program asked me to open the folder and exit the process (assumingly, the seeding process still runs in the background). I can open the downloaded files.

However, I would like to go back to the folder. I couldn't find it any more???
e.x. C:\Users\toey\AppData\Local\Microsoft\Windows\Temporary Internet Files
