Thanks Scott, this is helpful and good to know. In the meantime I have played a little with lsof on the command line, and it seems to sort of answer the question wether or not someone has a file open with authority... but it's very slow.
Just to enlighten me, why can't there be no absolute way to know when a file has been completed? I'm not doubting you, just trying to learn... is it because you can't predict what's going to happen right the second after you look? Your idea to have the other app flag me makes a lot of sense to me, thanks again, Rainer On Apr 10, 2011, at 17:53, Scott Ribe wrote: > On Apr 10, 2011, at 5:57 PM, Rainer Standke wrote: > >> Is there any way to tell if a file is done being written? > > In general, no.
