ফাইল আপলোড ও Nice Download লিংক

ফাইল আপলোড — Nice Download লিংক দেখাবে

আপনি নিচে ফাইল সিলেক্ট করুন। প্রতিটি ফাইলের পাশে “Nice Download” লিংক পাবেন — ক্লিক করলে ফাইল ডাউনলোড হবে। (Client-side ডেমো)

Tip: প্রতিটা ফাইলের ডাউনলোড ক্লিক করলে ব্রাউজার ফাইলটি ডাউনলোড করবে। এটি সার্ভারে আপলোড করে না — যদি সার্ভারে রাখতে চান নিচে server-backed উদাহরণ দেখুন।
