Copying any kind of files

Hello,

 

Just lately, I cannot copy/paste/transfer any files from the harddrive to a cd/dvd/flashdrive/etc.  I am running XP, XP  PRO, Windowx 7, Windows 7 PRO, all on different computers/laptops. All computers/etc have NIS 2011, or 2012, or 2013 on them.

All computers are completely updated. i have tried to copy/paste in many different ways, but I get error messages, can't even copy a text file.

I know how to copy/paste/burn to a flopy, cd, dvd, flashdrive, etc. I've tried using CDRW, CDR, DVD+R, DVD-R, flashdrive, etc....nothing works....

 

Is this a NIS problem, or a MICROSOFT problem?
