Where Does 4K Video Downloader Save Files and Settings?
4K Video Downloader output folder and settings on Windows and macOS, including Smart Mode defaults.
Last updated
4K Video Downloader saves where you tell it per download, or to one fixed folder under Smart Mode. Fresh installs default into your Videos library. Settings and license state live separately: registry keys on Windows, preference plists on Mac.
Smart Mode is the setting that matters. Configure format, quality and Save To once and every pasted link follows it silently. Without it, each download opens a dialog asking where to go.
Where 4K Video Downloader stores this, by platform
%USERPROFILE%\Videos\4K Video Downloader
Default landing spot for fresh installs; Smart Mode overrides it with whatever Save To holds. App settings live in the registry under HKCU\Software\4kdownload.com, which is also what you delete for a full reset.
~/Movies/4K Video Downloader
Same Smart Mode behavior as Windows. Preference files are com.4kdownload and com.openmedia plists in ~/Library/Preferences; remove those plus the app for a clean reinstall.
Frequently asked questions
How do I change the 4K Video Downloader output folder?
Open Smart Mode settings and change the Save To field, or pick a folder per download with Smart Mode off. Later downloads reuse the last folder until you change it again.
How do I download a whole playlist without clicking each video?
Turn on Smart Mode with your preferred format, quality and folder once. Every pasted link then downloads without prompts, which is the fastest way through a playlist.
How do I fully reset 4K Video Downloader?
Delete HKCU\Software\4kdownload.com registry keys on Windows, or the com.4kdownload preference plists in ~/Library/Preferences on Mac, then reinstall. Keep your output folder, since uninstalls leave downloads alone.
