The hidden files and folders that I have difficulty locating

You're already showing ordinary hidden items, but Windows treats protected operating-system files separately, and some locations can be inaccessible because of permissions rather than visibility. In File Explorer, open Options, choose View, select “Show hidden files, folders, and drives,” and temporarily clear “Hide protected operating system files.” Accept the warning, then search from This PC if you do not know the path. Enable file-name extensions so similarly named files are easier to distinguish. Do not delete or relocate anything under Windows, Program Files, ProgramData, or another user’s profile merely because it becomes visible; Windows or applications may require it. If a specific file still does not appear, confirm its exact path, OneDrive online-only status, and your account’s permissions. Re-enable protected-file hiding after troubleshooting. For a missing system file, repair Windows rather than manually replacing it or taking ownership.
