I have multiple folders that contain files that I am thinking is from the CSC. I had a hard drive sent off for recovery and they pulled everything out they could, 6 DVD's worth. 3 of these DVD's are full of folders that have files in them that Windows XP Professional does not recognize. How am I supposed to read a file when I have no idea what type it is, .doc, xls, ppt, etc.? Is there a way to read what types of files are on these DVD's
