In the scene where Jack has access to Ritter's computer, Jack is seen viewing and printing files. Then Ritter discovers Jack's diversionary phone call, so Ritter begins to delete the same files from the disk, and eventually clears the screen of the file Jack was accessing. Disk operating systems of all kinds do not allow an open file, the file jack was printing, to be deleted; thus, Jack should have been able to keep the file open as long as he wanted to and print or copy to another disk to use as evidence against Ritter. Furthermore, Ritter would have received an error message on his computer like, "CANNOT DELETE FILE - FILE IN USE", or some similar message, and not a "Deleting files *.*" message for the duration. The fact that the printer Jack was using ran out of paper is irrelevant.
