How to find the missing files in the system

In fact, I have encountered this problem many times before, that time is just work soon, because there is no work experience, do things to always absent-minded, a will this file do not know where to go, a will that file and I covered, a while is not know accidentally deleted which file. But at that time because of the computer technology is not very understand, so many times is to give up, or is in vain to scold, or in the case of no way to re-get once, anyway, they are menial.
But with the growing understanding of computer technology, I began to know that the original method of using System Restore can recover some lost files, but the premise is that you have set up the System restore point at that time, but now the system more and more intelligent, can be at any time for our system to set the restore point, We can recover selectively.
But on the other hand, the data in our computer is constantly increasing, that is, we need to retrieve the data before the current data line to be backed up, otherwise, found that lost this, there is no point, it sounds like a very troublesome!
But now, I began to know that a lot of third-party software also began to provide data recovery software functions, which I found on the internet is called the Calf File Recovery software tool, is a relatively good data recovery software, anyway I tried, the effect is good, plus this software behind so much praise, Everyone's experience is good, then also shows that this software is really worth recommending! The software has a video tutorial, we might as well look, very simple!
