Hello to all! I had a folder named "Myprogs" in partition E, which contained more than 300 C++ programs.
I don't know when, but I have permanently deleted my folder by mistake. Please tell me if there is any method by which I can recover my folder. I will be thankful to you.

There are quite a few programs that are available that have that capability, Google can tell you more. However remember that anything that has been overwritten since it was deleted will degrade the quality of what you can recover.
