In fact after you install Windows for the new school year, after 2 weeks again do not understand what is happening. Especially in folders of downloads. A bunch of books in archives it is not clear where and why.
Tried to create separate folders (for literature) and divide it by categories. After some time, still all the mess comes from. Just unfortunately, at this rate, I spend a few minutes of time sometimes, to dig up something useful, and when you find it you forget what you were looking for. And through a floor of year-year all forget the purpose of some files.
Maybe someone has a simple and effective way to keep the hard drive clean and "combat readiness"?
