I am currently running a long MD simulation (40 days) with Discovery in Materials Studio 5. It's about half way through and I wish to look at the trajectories with an external program. I therefore wish to download the .his file from the gateway server. It's around 5 Gb in size.  Are there any file handling issues with me downloading the file from the server? I don't want to create any issues with the simulation continuing.  For example, when the server serves the file does it do any file locking which might prevent the server writing the next trajectory snapshot?  Andrew
