Quite often when I try to empty my history folder (through tools-internet options-clear history). I won't clear. It doesn't happen every time. Any ideas?
Use a "cleaner" program that overwrites and destroys all data in the folder you request. The reason your history folder is not emptied when you ask could be a trojan or virus somewhere on your system
I've just tried it on mine and it wouldn't clear it. My Days to Keep Pages in History was set at 0. When I changed this to 1 and then clicked clear history it worked fine.
