The Compact Flash is mounted as drive C. Windows XP Embedded defines the directory structure, which is very similar to a standard Windows XP directory structure. There are a few directories:
/inetpub
Contains the FTP server and Web server administration scripts and root directories.
/inetpub/ftproot
Contains the files from the FTP site. There is also a shortcut on the desktop.
/batchfiles
Contains the Devcon.exe and driverswap batch file. These tools are useful for switching between MPI versions that require different device driver versions.
