Autoexec.bat boot.ini config.sys io.sys msdos.sys ntbootdd.sys ntdetect.com ntldr That list of files is present in the root directory of my DATA disk. No OS installed on it at all. I did not move or copy them there, at least not knowingly. These are similar to files I am accustomed to seeing in the root directory of a boot disk or partition. These files (with different dates and/or times) are present in the Vista partition root directory. Also present are a few folders with those uniques names created by whoever creates them (names like 0bc9d3bbd37024433211fb44) These contain folders like update (in one folder) amd64 i386 (both in 3 different folder, each pair with different date modified dates) Can anybody explain or make an educated guess as to why these files are here and how they got there?
