In the Blazor File Manager component, you are able to prevent the external drag and drop upload action for any types of files or folders by setting the DropArea property as null in the FileManagerUploadSettings class.

The following example demonstrates how to prevent the external drag and drop upload actions for all types of files in the Blazor File Manager component.

@using Syncfusion.Blazor.FileManager

<SfFileManager TValue="FileManagerDirectoryContent">
    <FileManagerAjaxSettings Url="https://ej2-aspcore-service.azurewebsites.net/api/FileManager/FileOperations"
                                UploadUrl="https://ej2-aspcore-service.azurewebsites.net/api/FileManager/Upload"
                                DownloadUrl="https://ej2-aspcore-service.azurewebsites.net/api/FileManager/Download"
                                GetImageUrl="https://ej2-aspcore-service.azurewebsites.net/api/FileManager/GetImage">
    </FileManagerAjaxSettings>
    <FileManagerUploadSettings DropArea="null"></FileManagerUploadSettings>
</SfFileManager>
