Resolved folder contents in blue

all of a sudden when i open my music folder some of the files are in blue with the rest in default black.i normally get blue when the file is duplicated but this time none are. any ideas please?

 

I think it signifies that the folder is compressed..........

 

If the file or folder name is blue then it means it was compressed. Right click the file or folder and select Properties. Click on Advanced and uncheck the box Compress contents to save disk space.

 

thanks

thank you problem was solved as suggested
