MAPI4Opera: Use Opera Mail as Default Client

Key Features

• MAPI4Opera is a system utility that enables the Opera web browser (specifically its M2 mail client) to handle \'Send To\' mail commands from other Windows applications.
• Normally, clicking \'Send to > Mail recipient\' in Windows Explorer opens the default system mailer; this tool intercepts that command and passes the file attachment correctly to Opera Mail.
• It bridges the gap between the Windows shell and the Opera browser, ensuring a seamless workflow for Opera users.
• This small utility is essential for fully integrating Opera Mail as the default email client on Windows.
