Check to see if you can start your computer using only command prompt and not starting Vista at all. The main reason for files not deleting is that there are Windows processes connected with it.

Using command prompt (this is for DOS but should be the same commands)

MS-DOS help and commands

The del commands are the ones you are looking for. E.g. navigate to your user and delete the incomplete folder - deltree incomplete

None of them say that they work for vista, simple way, anyone know how to back trach the computer, im just going to try the disk and deletin, ill post results

No luck, the back tracking feature is on XP i no that, i used it once, not sure where i found it and where to find it on vista

This has just got serious, my laptop's battery is of dodgy, it needs sorting out, i'd take it to my dads house when i go down for him to sort out but with the file, i can't, i need serious help, maybe i could use the feature to back track the laptop, but i don't know where it is, please, i realy need help now

Do you mean System Restore (to restore your computer to an earlier time)?

I don't use Vista, but have a look at the info below.
Using Windows Vista System Restore :: the How-To Geek

Getting into Windows Safe Mode

Out of curiosity, have you turned on Show Hidden extensions. There may be hidden characters in the file name. Tried renaming the entire file?

I asked one of my supper genius(no exagaration) mates and he told me, but just found out it only does system things:(, please, help me

2 pieces of advice:

if you were using a dual boot machine (you know, with 2 separate OS's on it) you could remotely delete it from the other OS..

try this, move the file into its own special folder, then using safe mode delete the folder

It won't move, anyn like copying, deleting, just keeps trying to calculate the time, never does I NEED IT SORTED FOR 2MORROW

How about drag & drop a file/folder of same name into same directory, choose replace.
Be sure you are disconnected from the internet, cable at back of computer if necessary. Did you try starting up from a startup disk? Or even a network for a lan if you are connected on a lan.
