I can't move big files from one partition to another

hi, I can't move big files from partition C to partition D, this in normal
operation;

I enter to secure mode and I can move the files
without any problem.


What could be?

I have kasperky internet security 2010.

Also I dont wish to format & install windows XP again.

cheers

No, just the window saying it left 5 seconds to copy/move the file
but never ends


What is the type/extension of these files etc?
videos, almost all .mpg & .avi



Since I can move/copy in secure mode, some aplication is just turtling the copy/move
process, lol

Do you by any chance have created a 'Restore Point' which is not too old (e.g. 10 days or so ago), if so, use it to restore your system to that time, perhaps that may help.
