What is a XAP file?
Project created with the Microsoft Cross-Platform Audio Creation Tool (XACT); saved in a text format and contains the intermediate form of the information produced by XACT; includes complete descriptions of wave banks (.XWB files), sound banks (.XSB files), and global settings (.XGS files).
XAP files can be opened and viewed in a text editor, but they should not be edited manually. Instead, project files should only be modified with XACT.
