As you know, there is one big bug of files operation for windows vista, including copy, move and delete files (or folders). Vista will take a long time to calculate how much time will take for these operations. This will cause slow files copy or move for big files. Many users complain this big bug.

There are some patches claims they can solve this problem. But I test them and find out they can’t resolve this problem really. In fact, the main reason of slow files copy/move for vista is the new service call “Remote Differential Compression”. Because it make all the files copy/move as the remote transfer, it will compress data first before files copy/move and will depress data in destination. This make files copy/move very complex and slow.

So now we know what reason cause the slow files copy/move in vista, but how to solve this problem properly. Please follow the instruction next:
1. Go in Control Panel / Programs and features.
2. Turn on or turn off Windows features.
3. Uncheck “Remote Differential Compression” and restart computer.

Now you can enjoy the more fast files copy/move than XP!
