27 <p><pre><font face="Consolas, Courier New">Usage: DDiff target1 target2 [options]
28Example: DDiff d:\dir1 d:\dir2
29Example: DDiff setup1.msi setup2.msi
30Example: DDiff patch1.msp patch2.msp -patchtarget target.msi
31Example: DDiff package1.cab package2.cab

33Options:
34 /o [filename] Output results to text file (UTF8)
35 /p [package.msi] Diff patches relative to target MSI</font></pre>

39 <p>The following types of inputs can be diffed:
40 <ul>
41 <li><b>Directories</b>: files and subdirectories are compared.</li>
42 <li><b>Cab files</b>: internal file list and files are compared.</li>
43 <li><b>MSI/MSM database files</b>: summary info, tables, and embedded binary and cab streams are compared.</li>
44 <li><b>MSP files</b>: summary info and embedded file cab are compared. When a patch target MSI is provided, the MSP's tables are also compared.</li>
45 <li><b>Versioned files</b>: Win32 file version is compared.</li>
46 <li><b>Text files</b>: if diff.exe is in the path, it is used to get a line-by-line diff.</li>
47 <li><b>Other files</b>: file size and bytes are compared.</li>
48 </ul>
49 All processing is done recursively. So a versioned file within a cab within an MSI within a directory will have meaningful diff results.</p>
