For planned installation of ScanDOAS in AK, it is likely that they will download the pak files using a custom script to a directory on same computer as the NOVAC Program. This is for couple reasons, 1) they would like to avoid giving a Windows computer access to the network, and 2) they want to be able to control how much bandwidth is used to ensure the constantly streaming seismic data is not disrupted by pak file downloads. Right now the NOVAC Program checks the Temp folder on start up for any unprocessed pak files, but it is only done once at start up. A modification of the software to periodically check the download directory (whether it is Temp or otherwise) is required. Perhaps the best way is to add an option in Communication Settings to allow polling from directory. If this option is selected then the software does not have to attempt an FTP connection to the instrument PC and can just look in the appropriate directory (Temp?) for the pak files.

Additionally, the software must be able to determine if a pak file is a completed file or not.
