ArcPad will open a new blank map. If you have another map open, ArcPad will
ask you if you would like to save any changes to the current map before
closing it.
Tip
Prepare your Data: Use the ArcPad Data Manager for
ArcGIS Desktop to prepare your data for ArcPad. With these desktop tools,
you can create subsets of your data, convert data to shapefiles and ArcPad
AXF files, and export legend symbology. The ArcPad Data Manager also
optionally creates an ArcPad map containing the selected layers.
