Visual Studio: Is there a way to collapse all items of Solution Explorer?

I know that I can use Arrow Keys to collapse items of solution explorer one by one, but I would like to know if there is a way to collapse all items with only one operation. I want to know it because, today I have a solution with 6 projects that have at least two hundred files and if I try to collapse them one-by-one I will have a hard time.

It appears to be built in by default in Visual Studio 2013 onwards.

If you have ReSharper installed, you can right click on the solution in the solution explorer, and select "Collapse All".

You can use PowerCommands for Visual Studio 2008

Right click on the project\solution on the solution explorer and choose Collapse Project:

Just use the number pad's Plus + and Minus - keys at the top-level node, to expand and collapse respectively (Note: * also expands the whole list.)

For the toolbox, you need to use * and / instead for expand/collapse. Go figure.

In VS 2019 just click Collapse All

If you have Resharper installed, there is an option called Collapse All and a shortcut key next to it.

Now this shortcut key will not work for you ! Unless you set it up using Tools > Options > Keyboard.

The command name is ReSharper_CollapseInSolutionExplorer.

Search using this command name and assign a shortcut key of your choice.

and you now have a shortcut key ready to use to collapse all items in your solution explorer.

I know I am a little late to this discussion, but this surely gonna help some one or other.

There's a macro at http://geekswithblogs.net/scottkuhl/archive/2007/04/09/111195.aspx for Visual Studio 2005.

The VisualStudio extension CodeMaid provides collapsing.

Download from VisualStudioGallery.

The current version only supports VS2010 or higher, but you can install older versions side-by-side.

Using Visual Studio 2017 and above

use shortcut

• Open Tools > Options or press Alt + T + O
• Under Environment tab > Keyboard (Also, you can create a shortcut for Tools.CustomizeKeyboard to open it directly)

To Collapse All

• Search for "SolutionExplorer.CollapseAll"
• Add a new shortcut for example Ctrl+Left Arrow,Ctrl+Left Arrow

To Expand All

• Search for "SolutionExplorer.Folder.CollapseAll"
• Add a new shortcut for example Ctrl+Right Arrow,Ctrl+Right Arrow

• Assign > OK

Visual Studio 2012 is out on 8/15/2012, so I suggest upgrading to that to get a fast "Collapse All" toolbar button previously available only in the Productivity Power Tools' Solution Navigator, which was sometimes too slow to be usable.

take a look on this

Use the Visual Studio extension that fits your version of Visual Studio. In my case (I use Visual Studio 2012) I use the extension Productivity Power Tools, but, unfortunately this exist only for VS 2010 and latter... For VS 2008 there is a similar extension: Power Commands.

Delete the *.suo and *.csproj.user files, and reopen the solution/projects.
