## Running both tools on the same Windows PC without duplicating checkpoints

You do not need to delete SD WebUI Forge or duplicate 100 GB of `.safetensors` files to switch to ComfyUI. Configure [extra_model_paths.yaml](https://comfy.ink/install/extra-model-paths-yaml-setup) so ComfyUI reads your existing checkpoints, LoRAs, VAEs, and ControlNets directly from disk.

Install the Windows desktop or portable build from [/download](https://comfy.ink/download) and point it at your existing model library in under two minutes.

## FAQ

### Can ComfyUI and SD WebUI Forge share the same models folder on Windows?

Yes. Edit `extra_model_paths.yaml` in your ComfyUI root folder to point `base_path` at your existing models directory so both apps load the exact same files.

### Does ComfyUI use less VRAM than SD WebUI Forge?

ComfyUI only keeps the active node's sub-model (CLIP, UNet, or VAE) in VRAM at each step and supports native FP8 and GGUF quantization, making it significantly lighter on 8 GB and 12 GB GPUs.
