Configuration

Vapourkit keeps user data under its application data directory. The exact root depends on the platform:

• Windows: a data/ directory beside the installed executable.
• Linux: ~/.config/vapourkit-gui/data/ for packaged AppImage builds.

App configuration

• App config: data/config/app-config.json - user preferences, model metadata, and encoding settings.
• Filter templates: data/config/filter-templates/ - .vkfilter files copied from the bundled catalog or created by the user.
• Queue: stored in the application data directory and managed by the Queue pane.

Workflows

Workflows are saved wherever you choose them through the Export dialog.

• Format: .vkworkflow (TOML)
• Contents: filters, model settings, backend, output settings, segment selection, and colorimetry settings

See Save & Reuse Workflows and File Formats.

Models

• Runtime location: data/models/
• Bundled models: copied there during first-run setup
• Imported models: added there by the Import Custom Model flow
• .onnx: source model used directly by DirectML and NCNN Vulkan, or used to build a TensorRT engine
• .engine: GPU- and driver-specific TensorRT engine

The AppImage itself is read-only, so Linux stores writable application data outside the mounted image.
