randix 0 Report post Posted December 28, 2017 New user. Windows 10. So I have created multiple folders, with sub-folders. More often than not, however, I canNOT get the folders to expand to show the sub-folders. And yes, I click on the arrow next to the folder, and yes, I DO have sub-folders. It just does nothing. Extremely frustrating. Share this post Link to post Share on other sites
