PCMCIA File Structure

The PC Card is formatted as a standard DOS drive and can be accessed using any
DOS compatible computer with a PC Card slot (now available on most notebook
computers). As with standard DOS drives, files can be stored in both the root
directory or in a sub-directory. The receiver creates and maintains directories and files
on the PC Card using the file structure illustrated in Figure 4.2.
Other files may be stored on the PC Card, although it is recommended that the PC
Card only be used for storage of data because the $PASHS,CLM and "Delete All"
will reformat the card and all files will be lost.
Almanac files are stored in the root directory, while all other data are stored in
subdirectories that are named for the day of the year in which the data was recorded
(for example "DAY077"). These subdirectories are also known as workday
directories. Multiple sessions collected on the same day will be stored in a single
workday directory. However, if the receiver detects that more than six hours have
elapsed between the previous session and the current session recorded on the same
day, then a new subdirectory is created (DAY077_1). The subdirectories are named
according to UTC time and does NOT take into account your local time zone.
