I have a windows 98 (SE i think) there is a folder in my D drive that takes up 555MB that has 20 files in it. I have no idea what it is and want to delete it because it takes up over half my drive. The 20 files are factory(then ".002" through to ".020" and ".pqi"). All of the files except factory.020 are 28.5MB and factory.020 is 11.9MB. All the files say open with and i could not find anything to open it with. The computer says the folder was last modified on 6/1/98 and the files are 9/11/99. I want to know what all these files are, what they do, and if i can delete them.
