Sometime in the last couple of weeks a bunch of files on my PC changed a little, the wording of the file turned blue BUT not all files in the folders changed, only some changed to blue other stayed black, there does not seem to be any reason or pattern, there are old files, new files, files saved on the same day, all kinds of file types, doc's pics etc some black & some blue. It does not seem to have any effect on the files but thats not the point, I dont know why some changed & some did not. Anyone have any idea's?
