Do mv and cp commands lock files in different ways

We have two processes, one which copies a control file into a folder and another which is polling this folder and reading the control files.

Sometimes they clash and the reader fails because the copy is still happening.

We have been told that we should change the copy to a move because the move command will lock the file in a "different" way so that clash won't happen. I have so far found no evidence that this is true.

Can anyone tell me if changing to a move will really fix the issue.

Thanks,
S
