سلام وقت بخیر
من برای بارگذاری تمامی فایلهای موجود در یک درایو یا فولدر و نمایش اونها توی فرم برنامه از کدهای زیر استفاده کردم و تمامی روشهای Parralel و تسک های موازی رو اجرا کردم ولی مشگل اینه که اگر تعداد فایلها زیاد باشه فرم تا اتمام بارگذاری هنگ میکنه نمونه کدها رو میزارم اگر میتونید کمک کنید تا فرم برنامه کاهش سرعت نداشته باشه ممنون
