When you open a folder in Windows 10 OS and press CTRL + A key, what happens?

Correct option is C

In Windows 10, pressing CTRL + A while inside a folder selects everything visible in that folder—this includes all files and all subfolders. It is a universal shortcut for "Select All" used across file explorer, text editors, and other applications.

Important Key Points:

1. CTRL + A is a standard keyboard shortcut to select all items in a given space.
2. In File Explorer, it includes all visible items: documents, images, folders, etc.
3. You can perform batch actions (copy, delete, move) after selecting all items with this command.

Knowledge Booster:

• Selecting only files or only folders would require manual selection or custom filters.
• There’s no restriction on selecting just the first 10 items—CTRL + A selects everything.
