The disk file in your computer's hard drive is emptied. How to recover

Recently colleagues to introduce a very good cleaning software, said that the general anti-virus software and optimization software can not clean up the disk garbage files are all cleaned out, and is the form of third-party software operation, simple operation, the effect is very good, the speed is very fast, so I was a little tempted. No way, usually my family's computer is a daughter-in-law and I used, for a long time, we are both your I do not care, my you do not care, the last computer in the garbage file is very much, a few days ago also received the computer tips, a full more than 10 g of garbage, it is time to clean up.
So recently I have a holiday, decided to put my hard drive to tidy up a bit, naturally I think of this software. But now no work, also not good call to ask people, so decided to study this software, but do not know where the operation is wrong, the final garbage is clean up, but I one of the disk of all the files are emptied out, I instantly have no words, what to do?
I am a bit dazed, but this disk file has a part or daughter-in-law files, what should I do? So I had to give the introduction of the software colleagues to call, did not expect the other side really have a solution, this Dragon Data recovery software is he introduced to me, the first to see is a software, I am also very worried, but download the use of this software I found that the operation of the software is almost a fool-like, not only simple operation, the effect is very good, in contrast, just that software is simply a weak explosion. It seems that in the future when you use third-party software, you still need to be careful!
