To close and save all open PowerPoint files at once, you can follow these steps:

Option 1: Using PowerPoint's Interface (Manually)

1. Save All Files:

   • Go to the File tab in the ribbon.
   • Click on Save All (if available). This will save all open presentations at once.

2. Close All Files:

   • After saving, you can either click Close on each file individually, or:
   • Use the Alt + F4 keyboard shortcut to close PowerPoint entirely, which will prompt you to save any unsaved files before closing.

Option 2: Using a Macro (Automated)

If you prefer to automate the process, you can use a VBA macro to close and save all open PowerPoint presentations. Here's how to set it up:

1. Open the VBA Editor:

   • Press <code>Alt + F11</code> to open the Visual Basic for Applications editor.

2. Create the Macro:

   • In the VBA editor, go to Insert > Module to create a new module.
   • Paste the following code into the module:
   vba

   <button class="flex gap-1 items-center select-none py-1">Copy code</button>

   <code class="!whitespace-pre hljs language-vba">Sub SaveAndCloseAll() Dim pptPres As Object For Each pptPres In Application.Presentations pptPres.Save pptPres.Close Next pptPres End Sub </code>

3. Run the Macro:

   • Press <code>F5</code> or run the macro manually from the "Run" menu in the VBA editor to save and close all open PowerPoint files.

This will save and close all open presentations without needing to do it manually for each one.

Option 3: Using Task Manager (Force Quit, Not Recommended)

If PowerPoint is unresponsive and you need to close all files without saving (be cautious, as this may cause loss of unsaved work), you can use Task Manager:

1. Press <code>Ctrl + Shift + Esc</code> to open Task Manager.
2. Right-click on PowerPoint in the Processes tab.
3. Choose End Task.

This will force PowerPoint to close, but it will not save your files.
