+## Sequential Upload
+
+The `sequentialUpload` property controls whether users can upload files one by one in a sequential manner in the Syncfusion File Manager control. 
+
+To enable sequential upload, set the `sequentialUpload` property to `true` in the `uploadSettings` configuration.
+
+When set to `true`, the selected files will process sequentially (one after the other) to the server. If the file uploaded successfully or failed, the next file will upload automatically in this sequential upload. This feature helps to reduce the upload traffic and reduce the failure of file upload. 
+
+The screenshot below shows that each file begins uploading only after the previous one completes. This demonstrates how the `sequentialUpload` property works in the File Manager control.

+The [autoUpload](https://ej2.syncfusion.com/documentation/api/file-manager/uploadsettingsmodel#autoupload) property controls whether files are automatically uploaded when they are added to the upload queue in the File Manager control.
 
 The default value is `true`, the File Manager will automatically upload files as soon as they are added to the upload queue. If set to `false`, the files will not be uploaded automatically, giving you the chance to manipulate the files before uploading them to the server.
