How to share Opera settings between Windows & Linux? (post original)

1. Copia los archivos de tu perfil a la partición FAT32 exceptuando opera6.ini y con un editor de texto cambia todas las rutas absolutas de archivos para reflejar la nueva ubicación en los archivos opera6.ini, accounts.ini & index.ini (estos dos últimos están dentro de la carpeta mail).
   
   
2. Copia los archivos de tu perfil a la partición FAT32, y con un editor de texto cambia todas las rutas absolutas de archivos para reflejar la nueva ubicación en los archivos opera6.ini, accounts.ini & index.ini (estos dos últimos están dentro de la carpeta mail) y ejecuta Opera (a través de Inicio >> Ejecutar) con la opción de linea de comandos /settings. Ejemplo: C:\Archivos de programa\Opera\Opera.exe /settings D:\Opera\profile\opera6.ini
