Three of the pairs are gz files, meaning were zipped (compressed) with gzip, and what appears to be the unzipped/extracted files are right there also.
You must determine if these are important files.

One rule I try to always use...

If I want to delete something, but not quite sure how important it is, create a subfolder called OLD or SAVE, and mv the file(s) there. That way, if in five minutes or later today something acts strange, I can easily mv it back.

yeah im guessing they are associated with YUM to update software and such but one file has not been updated since 2006. I was thinking of droping them on my desktop and they deleting them off the server then if something happens I can just upload them again.
