অনেকেই আছেন উইনডোজ 7 এ 2003 বা উইনডোজ XP তে 2007 ব্যবহার করেন। কিন্তু অনেকেই প্রথম বার হয়তো আমার মত 2007 এ .docx ফাইল সেভ করেছেন, কিন্তু বাইরের দোকানে মান্ধা তার আমলের 2003 ইউজ করছে। বিপত্তি হচ্ছে সে ফাইল সেই দোকানের কম্পু তে আর ওপেন হয়না, বাধ্য হয়ে হয় দোকানে নতুন করে compose করি !!
এর সমাধান আমি পেয়েছি---
সেটা হল,
*.docx কে আপনি Office 2003 তে ব্যবহার করতে পারবেন, এর জন্য আপনাকে একটি কম্পটাবিলিটি প্যাক ইন্সটল করতে হবে।
এজন্য মাইক্রোসফটের নিজস্ব ওয়েবসাইট http://download.microsoft.com থেকে কম্পটাবিলিটি প্যাক ইন্সটল ডাউনলোড করে ইন্সটল করুন।

অথবা এই লিংক সরাসরি।

আর নিচের এই লেখা গুলো কপি করে পেস্ট করে দিলাম । কোনও ভুল হলে জানাবেন।
