Unlocker & Teracopy
Unlocker runs in the background and when you try to delete something and get a “file in use” or “permission denied” even though you are a local administrator it automatically kicks in. You will get a window showing what the cause of the error is and options to get rid of it by removing the cause for the error.
Teracopy is a replacement for the standard file copying/moving system which allows for extremely faster copy/move operation. If you every tried to copy a large file from/to another system from Vista over a wireless LAN you should automaticlly see the value this has. Yes, SP1 improves that issue however it still doesn’t do it as well as it does on XP.
