When I was browsing around on my Windows computer the other day, I noticed some files are displayed blue and others are black when I view them in My Computer. I'm sure there is a reason why they are different but am not sure why. Should I be concerned?
I can understand why you might be concerned.
There is nothing worse than that sinking feeling when you see something out of the ordinary on your Computer hard drive that you never saw before. Immediately you start to think of a virus or spyware.
The good news is, this is normal and your PC is fine.
What really is going on here is that you are viewing files that have been compressed by Windows. And, more than likely, one of your folder view options settings is set to display compressed NTFS files in color.
Let's take a look at what I mean.
