-Split WIMs are not fully supported.  These can be used to split up a WIM to fit

-\fBimagex join\fR to combine split WIMs, but you cannot yet create split WIMs or

+The most important difference is that this version of \fBimagex\fR cannot
+capture and restore Windows images losslessly because file permissions and
+alternate file streams are ignored.  This is because Microsoft designed the WIM
+format to be specific to their NTFS filesystem and the Windows security
+model/API, which is difficult to support in a non-Windows program.  You can
+still create images of Windows PE, however.
+
+See the documentation for each subcommand of \fBimagex\fR; in some cases they do
+not do exactly the same thing as imagex.exe.

 
 Some features, such as the ability to keep files hard-linked when they are
 extracted from a WIM, are not available in Microsoft's version of imagex.

+Also, doesn't seem to be an equivalent of \fBimagex join\fR in Microsoft's

+you export all images at once.
+
+Microsoft's version has some weird limitations, like it won't let you extract a
+WIM on a shared folder, and it requires some commands to be run only from
+Windows PE and not from regular Windows.  This version does not have these
+unusual limitations, although it won't actually run on Windows anyway.
