Why does a folder name becomes blue..?

• It is a way of saving the Disc's space. If the folder or file is in blue, then it means the particular folder or file has been compressed to save the disc space. 

• This property  applied on your folder can be changed, but if the C drive is running short of memory then this option will help you to generate some more space. 

• Other wise you can change it easily by right clicking the folder, then go to

Folder ---|| Properties ---|| Advanced ---|| Uncheck the first box below compress or encrypt attributes---|| Save Changes

• You will get your folders in normal black color

• Similarly, the folder can be of a GREEN COLOR, if it has been encrypted. So, again we can check this property by the same technique described above.
