    Long story short, yes. But I suffice to say, its a bit over your head.

    There are several ways - some much harder than others.

    The easiest I can think of is to simply inject your code into the process that has the file open. A single process can open a file multiple times without sharing.

    If you don't know which process has the file open, it gets a little harder
