In this video, I reinstall FileBrowser on the latest TrueNAS SCALE 25.04.2.3 and fix the “wrong credentials” problem that many of you faced after the update. I start from the basics: I create an Apps dataset (with the Apps preset) for application files, then I build a proper SMB share dataset (with the SMB preset) and set a quota so the share stays controlled. After enabling and verifying SMB services, I create a dedicated SMB user, validate permissions on the dataset, and test access from Windows using the NAS IP (\\server-ip) to confirm read/write is working. Once SMB is clean, I install the FileBrowser app the correct way—mapping datasets properly and not touching the users/groups section during install. I show you where to get the first-time admin password from the container logs, then I log in and immediately secure the setup by creating a new admin user and disabling the default admin permissions (important: don’t delete the default admin account). Finally, I mount SMB shares directly into FileBrowser by editing the app storage and adding SMB/CIFS mount volumes—both from the same NAS and even from other servers—so you can browse, upload, copy, and manage files from one simple web UI.
