Question
I took a filename as a command line argument, now I want to check the presense of any file with same filename in the current directory. How do I do that?

Answer
Rakesh , Thank you for your question.

1. Open the file for reading, using CreateFile with the GENERIC_READ, FILE_SHARE_READ, OPEN_EXISTING, and FILE_ATTRIBUTE_NORMAL flags.

2. Close the file.

3. If the result of the Open was FALSE, the file or folder does not exist.
