One day my cousin sister send me the some of my important paper in PDF file after that I was trying to open that file again and again but I not able to open it, same day in the evening when husband came back to home I just told all problem to him.
So he told me that if you want to open PDF file then you have to download Adobe Reader and then install it on our computer and then you are able to see your document and then I just download and use it, I am happy because I able to see and open all my important documents, Adobe Reader is the best software to open all the PDF Files.
