Atlas File
This is the "raw" file format for layer after layer of cartographic and hydrographic data on our CDs. You never have to work with these files directly. MapCreate pulls data from these files to display the Master Map you see in the main window on your computer. The program combines the information from a Map Border File with the Atlas Files to make Custom Map Files for your GPS unit.
NOTE: MMC Card Formats
If you have an older MMC that has been formatted by a parallel port Lowrance MMC Interface card reader, the card format may not be compatible with your newer USB port MMC card reader. If that's the case, you can preserve your historic GPS data by copying it to your hard drive with your older parallel port reader. The older MMC can then be reformatted so it will work with the newer USB card reader. To reformat an MMC, refer to the instructions that came with your USB MMC card reader or your sonar/GPS unit.
If you ever have to format your MMC card, you should know that MapCreate, as well as Lowrance and Eagle GPS products, will only read cards that are FAT formatted. MMC cards formatted using FAT 32 or NTFS will not work with these products.
WARNING:
You should never format an MMC containing a Navionics chart. Formatting the MMC will permanently erase the chart from the card.

Important Notes About File Size
The size of a Custom Map File is important. It must be small enough to fit on the MMC (MultiMedia Card) that your GPS uses for data storage.
