While on my Mac, I use the list view in Finder a lot. One thing I had mixed feelings about is the tree-like view that expands folders. It was great, but I wanted a way to quickly collapse or expand folders – and I found out how!
So to quickly expand or collapse folders, all you need to do is to press the left or right arrow keys while a folder is selected. This will expand or collapse it. But I’m guessing that you already knew that – the great thing that I found is, you can first select all folders by pressing ⌘-A, and THEN press the left or right key to expand or collapse every folder.
Neat 😀
HI,
JUST PRESS * KEY TO EXPAND OR COLLAPSE A TREE, FOLDERS WHAT EVER IT MAY BE
ITS DONE
THANK YOU. I LOVE YOU SO MUCH. YOU ACTUALLY HAVE NO IDEA HOW LONG I’VE BEEN NEEDING TO KNOW HOW TO DO THIS.
YOU ARE AN AMAZING PERSON <3 :')
If you hold down the option key while pressing the right/left arrow key, you will expand/collapse all subfolders, as well.
