File Explorer in Windows 11 has usability issues, particularly with sluggish search functionality and problems accessing networked drives. Users often experience drives disappearing after reboot, inaccessibility to files, and freezing of File Explorer, with error codes like c0000375 indicating deeper issues. The networked drive feature relies on outdated technology, as Microsoft has deprecated older protocols like SMBv1, complicating file sharing. Users can mitigate freezing by restarting File Explorer and ensuring network settings are correctly configured, such as setting Wi-Fi to private and enabling file sharing options. Excessive pinned items in Quick Access can cause crashes, and clearing the cache may resolve these issues. Alternatives to File Explorer, like XYplorer and File Pilot, can provide better access to networked drives. Overall, the challenges stem from outdated technology and the corruption of the Quick Access cache, with third-party solutions available for relief.
