What’s MSCE? I found “MSCE” in the *.000 file of Windows Mobile installation file (*.cab). I go through the search result of Google. There is no description of MSCE.

Why I care the MSCE file? During I implement the theme package function of CVE (CHome Visual Editor). I need to package the files into a Windows Mobile cabinet file. Package files into a normal is easy. There are many component to do this. But a Windows Mobile cabinet contains a *.000 file. This should be the binary version file of cabinet *.inf.

Following is the C# structure definition of the MSCE file (incomplete, cannot compile):

    [StructLayout(LayoutKind.Sequential)]
    public struct MSCE
    {
        /// <summary>
        /// Initializes a new instance of <see cref="MSCE"/>.
        /// </summary>
        public MSCE(ushort blockCount)
        {
            Header = "MSCE";
            BlockCount = blockCount;
            Entries = new Entry[25];
        }
        private string Header;
        //[FieldOffset(0x04)]
