Hi,
Thank you for writing to Microsoft Community Forums.
A folder cannot be opened unless you click/double click or select and press the enter key. However, while dragging a file or a folder in file explorer,
if you hover the mouse over the target folder in the left pane (the navigation pane), it should expand the folder to show its contents (Subfolders, files).
If folders do not expand in the navigation pane, click on the
View menu item at the top left corner of the explorer window, click on
Options submenu item in the ribbon and choose Change folder and search options which should open the
Folder Options window.
Click on the
View tab of Folder Options window.
Scroll down and check the checkbox for
Expand to open folder under Navigation pane.
Hope it helps.
Feel free to contact back in case you need any further assistance with this issue and let us know if you got the help you needed by clicking
