More than 10 days ago, I restored my system in safe mode to a certain restore point becuase windows explorer was not responding. After system restore was completed, I lost a folder (named Data), and all the files it contained, which I created in C:\Windows.
Why would system restore do that?
And is there a way to retrieve my files??
Never put a file you want later in the Windows folder... always store it in your User folder. I'm not absolutely sure of this, but I imagine what happened is System Restore found a folder in C:\Windows that wasn't there before the last restore point. System Restore most likely removed the folder because it didn't think it should be there.
