Why let me found it??

Today...
I back from my home town...
I will take my computer to format...
So I deleted all of my Documents in my computer...
Suddenly... I saw a folder...
It containing all the history of my msn...
Before that... I tried to found it...
But I cant Found it...
Now... Why God let me FOUND it??
I reviewed the history from him and me...
I really so miss that time...
I am feeling frustrated...
Haiz...
I wish all of his memories in my brain...
As the USB... Just Click the delete click...
All of the memory will clean...
Haiz...
