I have a Photoshop file with a lot of groups inside and inside those groups even more groups. To get to a layer that I want is a looong way, and after that it's even longer to collapse back so I can get to another layer. I was wondering if there is a way to collapse and expand all groups at once?
To open/close all layer groups (folders) at the current level of hierarchy: Cmd-click the arrow next to the group
This is handy when you want to open/close, say, all the top-level groups without disturbing the open/closed state of any groups nested within them.
To open/close all layer groups nested within the current one: Opt-click the arrow next to the group
This is nice when you want to open/shut a bunch of nested groups, without affecting any that lie outside the target group.
To open/close all layer groups, period: Cmd-Opt-click the arrow next to a group
So, to keep things simple: when in doubt, Cmd-Opt-click a group’s arrow and you’ll collapse/expand all groups.
*On Windows please substitute Ctrl for Cmd and Alt for Opt.
Ctrl + Click on the small arrow will expand collapse the top most folders in the layers pallete, but will not expand sub folders within these.
