For a few years, I've been annoyed by how long it took to do a full scan on windows 10. After watching the progress bar that showed what was being scanned, I found that the problem was the 3D program "Poser". Last week, I simply opened DRIVE C and scanned all the folders except the Poser files and the job was done in just over an hour! I scanned Poser a couple of days later by itself and that only took a few hours. This was an easy solution that I tried again today with no problems.
