Appendix A : File Format
NavDive stores its files in a particular format on the SD memory card. This next section describes the file
structure and each particular file format. This information is not necessary to operate NavDIve – it is
being provided for users that want to use the data created by NavDIve for other purposes.
Basic directory structure
When the NavDive card is formatted using the NavDive Log application software, it creates the following
file structure on the card:
Destinations (folder)
Saved Paths (folder)
Saved Positions (folder)
Descriptions.txt (file)
The Destinations folder is used to hold all of the destination files for NavDive. These are files that
contain all of the target locations for a particular site or area.
The Saved Paths folder contains all of the files saved by NavDive when using the tracking feature.
The Saved Positions folder contains all of the files saved by NavDive when specific positions are saved
during the dive.
The Descriptions.txt file holds all of the text descriptions used when saving a position with NavDive. This
is a text file that can be edited to add or edit new descriptions as desired.
When the card is initially formatted, the Destinations, Saved Paths, and Saved Positions folders are all
empty.
