+> {"code": -2804, "message": "Loading the WebTwain css files failed."}
 
-<strong>Steps:</strong> In the below example we will assume the original Resources folder is located at '<strong>../{Project Directory}/Resources</strong>', and you want to change it to '<strong>../{Project Directory}/Newfolder/ResourcesTest</strong>'.
+it usually means that Dynamic Web TWAIN cannot locate its runtime resources.
 
-Step 1. Please make sure the structure inside 'Resources' folder stay unchanged.
+This article explains how Dynamic Web TWAIN locates its resources and how to correctly configure the resource path after moving or renaming the **Resources** folder.
 
-Step 2. Change the relative path in your page where you reference the js files, for example:
+## How Dynamic Web TWAIN loads its resources
 
-```html
-<script src="Resources/dynamsoft.webtwain.initiate.js"></script>
-<!-- or your own operation js file --> 
-<script src="Scripts/DWTSample_BasicScan.js"></script>
-<script src="Resources/dynamsoft.webtwain.config.js"></script>
+Dynamic Web TWAIN loads its resources in two stages.
+
+1. Your HTML page first loads the two entry JavaScript files.
+
+2. After initialization, Dynamic Web TWAIN loads all remaining JavaScript files, CSS files according to the value of `Dynamsoft.DWT.ResourcesPath`.
+
+The loading process is illustrated below.
+
+```text
+index.html
+    │
+    │ loads
+    ▼
+dynamsoft.webtwain.initiate.js
+dynamsoft.webtwain.config.js
+    │
+    │ ResourcesPath = "xxxx"
+    ▼
+Dynamic Web TWAIN
+    │
+    ├── loads CSS files
+    ├── loads additional JavaScript files
+    ├── loads WebAssembly files
+    └── loads other runtime resources
 ```
 
-Modify as below:
+> **Note**
+>
+> `ResourcesPath` does **not** determine where `dynamsoft.webtwain.config.js` is located.
+>
+> Instead, it tells Dynamic Web TWAIN where to find all of its remaining resources after initialization.
+
+## Example project structure
+
+Suppose your project is organized as follows.
+
+```text
+Project
+├── HTML
+│   └── index.html
+└── DWT
+    └── Resources
+        ├── dynamsoft.webtwain.config.js
+        ├── dynamsoft.webtwain.initiate.js
+        ├── dynamsoft.webtwain.install.js
+        ├── addon/
+        ├── src/
+        ├── dist/
+        └── ...
+```
+
+In this example:
+
+- `index.html` is located in the **HTML** folder.
+- All Dynamic Web TWAIN resources are located in **DWT/Resources**.
+
+The internal structure of the **Resources** folder must remain unchanged. You may move or rename the folder, but do not modify its contents.
+
+## Step 1. Reference the entry JavaScript files
+
+Because `index.html` is located inside the **HTML** folder, the two entry files should be referenced using the following relative paths.
 
 ```html
-<script src="Newfolder/ResourcesTest/dynamsoft.webtwain.initiate.js"></script>
-<!-- or your own operation js file --> 
-<script src="Scripts/DWTSample_BasicScan.js"></script>
-<script src="Newfolder/ResourcesTest/dynamsoft.webtwain.config.js"></script>
+<script type="text/javascript" src="../DWT/Resources/dynamsoft.webtwain.config.js"></script>
+<script type="text/javascript" src="../DWT/Resources/dynamsoft.webtwain.initiate.js"></script>
 ```
 
-Step 3. The same change needs to be done in *dynamsoft.webtwain.config.js* file. Add/uncomment the following line, then change 'Resources' (to 'New folder/ResourcesTest' as in this case):
+## Step 2. Configure ResourcesPath
+
+Open the following file.
+
+```text
+DWT/Resources/dynamsoft.webtwain.config.js
+```
+
+Locate the following line.
 
 ```javascript
 Dynamsoft.DWT.ResourcesPath = "Resources";
 ```
 
-Modify as below:
+Change it to the same relative path used by your HTML page.
 
 ```javascript
-Dynamsoft.DWT.ResourcesPath = "Newfolder/ResourcesTest";
+Dynamsoft.DWT.ResourcesPath = "../DWT/Resources";
 ```
+
+## Why do I need to configure both?
+
+The two paths serve different purposes.
+
+| Configuration | Purpose |
+|---------------|---------|
+| `<script src="...">` | Loads the two entry JavaScript files from your HTML page. |
+| `Dynamsoft.DWT.ResourcesPath` | Tells Dynamic Web TWAIN where to load all remaining runtime resources after initialization. |
+
+Even if the two JavaScript files are loaded successfully, Dynamic Web TWAIN will still fail to initialize if `ResourcesPath` is incorrect.
