As we all know, there is a big bug in Windows Vista concerning file operations, including copying, moving, transferring or deleting files (folders). Vista will take a lot of time and run very slowly when performing these operations. Especially for large files, it can be described as unbearable compared to XP, thus causing dissatisfaction among many users. The symptoms are表现为: before the operation, there will be a "calculating remaining time" dialog box, which takes quite a long time, thus slowing down the operation process and even causing the system to stall, hang or stop responding.
