From the doc: 'In the latest version of CrackFTP i put a 'shit' named a timer. I remove it for do a more powerfull FTP Cracker. I remplace it by a simple code for the program run at the maximum speed of your modem. I put a progress bar for see when you finish. I put some other personnal code for a more good CrackFTP. I wish you like this program.'
