Hi Dinesh Kaushal ,
Welcome to Microsoft Q&A platform and thanks for raising your concern here.
Unfortunately , your screenshots are not visible . Could you please share the images again , kindly make sure you provide space between two images and also between image and next text lines.
What I can assume from the question is that Get Metadata activity is not giving you expected result . Please correct me if my understanding is wrong.
Kindly check if your dataset is pointing to folder or file. If it's pointing to a folder , it will tell about the existence of that folder. If it's pointing to a particular file, it will just tell about the existence of that particular file.
Check this thread for better clarity.
