If you are a solo user on Windows who wants a modern alternative to File Explorer, choose Files. Its sleek WinUI 3 interface, tabs, and dual panes provide a significant upgrade over traditional file management options, making your workflow more efficient. However, keep in mind that it's Windows-only, and if you require advanced features like scripting or FTP access, you should look elsewhere.
On the other hand, if your priority is managing photos and videos with a focus on privacy, opt for immich. It’s an excellent choice if you’re tech-savvy and comfortable with self-hosting since it gives you complete control. Just be aware that setting it up requires some technical knowledge and may not offer as many integrations as cloud-based options. If you prefer a more straightforward, cloud-based solution or need extensive third-party integrations, immich may not be the right fit for you.
