I am an electronic engineer and a computer programmer.I usually download a lot of useful ebooks ,electronic datasheets and source codes from internet. But now I found out that if I need some information which I downloaded from internet into my computer, I couldn't find it. Ironically, If I don't need it, I can find it from my computer, and sometimes even several copies of them. Therefore, I need a powerful software to manage my data. I have spended a lot of time to search this kind software, but I find no such things on Dismayingl. So I decide to do it by myself and I name it Pioneer Files Management Assistant(PFMA).
