Datasheet manager v1.1

Preface: 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).
PFMA is an easy-to-use alternative to the standard windows file manager. This program will help you with daily work in Windows. Here you can find some function to manage your ebooks, data sheets, images, MP3, Videos,daily documents and ext.
