SNAP saves two output files for each successful snap-try: the original namelist file, and a binary file containing all the profile and scalar input and output values. These files are managed as part of the TFTR optical disk system. All of the SNAP utilities know how to find these files, so you needn't be concerned with where the files reside. Note: A new snap-try number is defined, and the output files written, only if SNAP completes successfully. So if SNAP aborts half-way through your run, no archive files will be written.
