yesterday i downloaded some videos from youtube.com and when i copied them to this folder, i could access it no more. The symptom is that whenever i double-click the folder, it takes almost indefinite time to access. In fact, the laptop nearly hung. I had to use task manager to shut down the explorer.exe(i saw that the CPU usage of explorer.exe was 100%). I couldn't delete the folder either, because when i did so, the laptop hung too. When i looked into Event Viewer, i saw announcement like this: Event ID 7000: the HDD&SSD access service failed to start due to the following error: the system cannot find the file specified.
And this doesn't happen to all folders and files. It just happens to the folder to that i copied the videos from youtube.
Please tell me, what am i supposed to do now?
