Learning is no so difficult in this time of technology. Just log on to internet and all the information is right in front of you, but the difficult thing is to choose the right thing at the right time. Even after so many years I am still learning how to do exact searching.
My younger brother asked me about what is file extension cache, I know so much about computers but the exact definition was not coming in my mind at that time, so I told him to come after half hour. I am glad that I found your website, the definition of file extension cache was so precise and to the point. But it was the most exact way of explaining in exact words. Your way of explaining about file extension cache and other file extensions is very good. I was able to tell my kid brother about it just because of you.
I also tried your software, and it is really amazing. The whole process was really easy just like you have explained. I am very impressed by your website and product. In my view you are doing amazing job, will definitely come back to you for knowing about other file extensions.
