 The word **_model_** has many different meanings. Here, it means a data file carrying information that is required for a node graph to do its work. Specifically, it’s a data structure that _models_ some function. As a verb, to model something means to represent it or provide an example.
 
 The primary example of a model data file in ComfyUI is an AI **_diffusion model_**. This is a large set of data that represents the complex relationships among text strings and images, making it possible to translate words into pictures or vice versa. Other examples of common models used for image generation are multimodal vision and language models such as CLIP, and upscaling models such as RealESRGAN.

 ### Using Models in ComfyUI
 
 1. Download and place them in the ComfyUI program directory
     1. Within the **models** folder, you'll find subfolders for various types of models, such as **checkpoints**
     2. The **ComfyUI Manager** helps to automate the process of searching, downloading, and installing
     3. Restart ComfyUI if it's running
 2. In your workflow, create the node appropriate to the model type, e.g. **Load Checkpoint**, **Load LoRA**, **Load VAE**

 ## Auxiliary models
 
 Model functionality can be extended with auxiliary models. For example, art directing a text-to-image workflow to achieve a specific result may be difficult or impossible using a diffusion model alone. Additional models can refine a diffusion model within the workflow graph to produce desired results. Examples include **LoRA** (Low Rank Adaptation), a small model that is trained on a specific subject; **ControlNet**, a model that helps control composition using a guide image; and **Inpainting**, a model that allows certain diffusion models to generate new content within an existing image.

   <Accordion title="Why can't I find my model?">
     If you've installed a model but can't find it in ComfyUI, try these steps:
 
+    - Verify the model is in the correct location:
+      - For **ComfyUI Desktop**: Go to **Help** menu → **Open Folder** → **Open Model Folder** to check the model installation path
+      - Ensure your model file is placed in the correct subfolder (e.g., `checkpoints`, `loras`, `vae`)
     - Press the `r` key to refresh node definitions so ComfyUI can detect the model
     - Restart ComfyUI
     - Ensure the correct model is selected in the model loader node

 ## 辅助模型
 
 模型功能可以通过辅助模型进行扩展。例如，艺术指导文本到图像的工作流程以实现特定结果，单靠扩散模型可能会很困难或不可能。额外的模型可以在工作流程图中优化扩散模型，以产生所需的结果。示例包括**LoRA**（低秩适应），一个针对特定主题训练的小模型；**ControlNet**，一个使用引导图像帮助控制构图的模型；以及**Inpainting**，一个允许某些扩散模型在现有图像中生成新内容的模型。

   <Accordion title="为什么找不到我的模型?">
     如果您已经安装了模型但在 ComfyUI 中找不到,请尝试以下步骤:
 
+    - 验证模型是否在正确的位置:
+      - 对于 **ComfyUI Desktop 桌面版**: 前往**帮助**菜单 → **打开文件夹** → **打开模型文件夹**来检查模型安装路径
+      - 确保您的模型文件放置在正确的子文件夹中(例如 `checkpoints`、`loras`、`vae`)
     - 安装模型后点击快捷键 `r` 来刷新节点定义,以便 ComfyUI 可以检测到
     - 重启 ComfyUI
     - 确保在模型加载节点对应的模型有被选中
