Most defragmenters either lock the file while it's being defragged or they 
stop defragging if you open the file for writing while they're defragging it.

That's more because bits of the kernel keep physical locations of files in 
memory (like swap, or root directory, or whatever).  Also, if you have the 
file open for writing (like the registry, say), then it's rough to defrag 
while it's being written.  Which is why (for example) the "page file 
defragmenter" runs during boot rather than live.
