I was testing some batch files using the command prompt. I used Windows Explorer to rename the files. However, when I went back to the command prompt and entered "dir", the file names did not update. They appeared with the previous name even though in Windows Explorer they had definately changed. Also, I edited some of the batch files by right-clicking on them in Windows Explorer and choosing edit. I saved the files and then opened them again to make sure the changes were there. However, when I went back to the the command prompt the files had the old names and content even though they did not in Windows Explorer. I ended up having to reboot. Our programmer has also experienced something similiar when she tried to update a program and icon. The new icon ran the old program, even though the old program had been renamed and removed. What could be happening? Is there some kind of cache that can be cleared?
