ExtensionPrefs.apx is a cache of information extracted from extensions/modules when they're loaded for the first time, so that ArcPad knows what each extension does.Then it can make a future decision to delayload them to conserve memory.

From a C++ perspective, all extensions/module implement APExGetProperty() that tell ArcPad what those extensions do. When we load an extension/module record what each extensions's responses were to APExGetProperty() and save them to ExtensionPrefs.apx.

Part of an ArcPad Extension Preference file (.apx) that delayloads all extensions
