## Removing Monaca Localkit (for Windows)
While uninstalling Monaca Localkit, you might not be able to remove its remaining files. In this case, please remove them manually from `Program Files` folder.
## Incomplete files and folder structure
Monaca/Cordova projects initially consist of the following files and folders:
| File/Folder | Description |
| ------------ | --------------------------------------------------- |
| `www/` | Storage folder for the main body of the application |
| `config.xml` | Cordova configuration file |
In this section, we will talk about how to fix your project if the `www/` or `config.xml` file is missing.
### Missing www folder
#### For standard projects
The user should create a `www` folder in the root of the project or restore a previous backup of the folder.
#### For Webpack projects
`www` folder will be created automatically during the transpiling process. Transpiling is triggered automatically after selecting a project from the project list in the Monaca Localkit if the option is enabled.
### Missing the config.xml file
{% hint style="info" %}
This solution works only if your project exists on Monaca Cloud.
{% endhint %}
1. From Localkit, select a project from the project list.
2. Click **Download** and the `config.xml` file will be restored.
### The preview window is not refreshing
The problem might be occured with Localkit 4.1.0 and up. Prior to this version, the preview window is served with `file://` protocol from the project file. However, this `file://` is not supported for project using `module` javascript such as the project using `vite` tool. Therefore, in Localkit 4.1.0, we have switched to `http://` protocol to support newer tool and framework. With this change, there might be some browser cache problems causing the preview windows to remember the previous served projects not the current one as the url is using the same address (by default ) for all the projects.
To resolve this problem, you can "disable cache" in the chrome developer tools of the preview window and click "refresh" to reload the preview window when needed.
Disable cache and refresh preview window
