2004 = year
250 = Day of that year
g = hour of that day (g = 6th hr)

This ZIP file contains the RINEX data for each 60 minute session for the year 2004, day 250 of that year and the 7th hour (6am to 6:59am) of that day indicated by the "g" at the end of the file name. Time of the stored file is related to UTC time. At the end of each UTC day there will be 24 individual data files with 60 minutes of data (1 for each hour a thru x), plus a single file (ie: mvcc2500.zip) containing the entire days data.
