The Windows VFS (Virtual File System) feature uses the nextcloud service to present files as on-demand stubs without downloading them — only file metadata is synced until you open a file.
Account credentials and sync folder mappings are stored in %APPDATA%\Nextcloud\nextcloud.cfg — back this up to migrate sync config.
Shell extension overlays (sync status icons in Explorer) are registered under HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\ShellIconOverlayIdentifiers.
