- Product
- File Explorer
- Device & OS
- not provided
- Scenario
- Moving files between folders using the drag and drop method in the file manager.
- Observed behavior
- The Documents folder and other directories no longer display expandable subfolders in the left navigation pane.
Ensure you have File Explorer open on your desktop. If you have recently updated your system or reset folder views, these settings may have reverted to their defaults.
Enable 'Show all folders' in Folder Options
This standard configuration adjustment will immediately restore the expand and collapse arrows to your File Explorer navigation pane.
Windows File Explorer allows you to customize the navigation pane's behavior. By enabling the option to show all folders, the system will render the complete folder tree, including the missing dropdown arrows for subfolders.
In the File Explorer window, click on the 'View' tab located in the top menu ribbon, then click on 'Options' or 'Folder Options' on the far right.
In the Folder Options dialog box that appears, click on the 'View' tab at the top to access advanced settings.
Scroll down through the 'Advanced settings' list until you find the section labeled 'Navigation pane'.
Check the box next to 'Show all folders'. Click 'Apply' at the bottom right, and then click 'OK' to close the window.

Enhance Your Document Management with WPS Office
While resolving File Explorer issues helps with general file management, a better office suite makes organizing your actual work much easier.

Frequently Asked Questions
Why did the expand arrows disappear from File Explorer?
This commonly happens if the folder view settings were accidentally reset, after a major system update, or if 'Show all folders' was unchecked in the advanced Folder Options.
Can I expand folders using keyboard shortcuts?
Yes. Once you select a folder in the navigation pane, you can press the Right Arrow key on your keyboard to expand it and view subfolders, and the Left Arrow key to collapse it.
Does enabling 'Show all folders' also show hidden files?
No, enabling 'Show all folders' only forces the navigation pane to display the full folder structure. To view hidden files and folders, you must separately enable 'Hidden items' from the View tab in File Explorer.
