You can know it only if the file was opened through a share. I mean: do it without trying to open the file and trap the error.

If you really want to do it this way, see my FAQ about "Who has what file opened on the netwrok" in the Files section.

But, Edward's solution is better because it's simple, it's bullet proof and... it's used by almost everyone. BTW, you can use this very simple method to be sure that your app is opened only once by the same user (which may not be on the same computer!!).
