.SH NAME
@IMAGEX_PROGNAME@-mount, @IMAGEX_PROGNAME@-mountrw, @IMAGEX_PROGNAME@-unmount \- Mount and unmount an image from a WIM archive
.SH SYNOPSIS
read-write mounted WIM, especially deleting large files, it is suggested to
provide the \fB--rebuild\fR option to \fB@IMAGEX_PROGNAME@ unmount\fR to force the WIM to
be rebuilt, or else run \fB@IMAGEX_PROGNAME@ optimize\fR on the WIM afterwards.
+.PP
+wimlib v1.6.0 and later can mount version 3584 WIMs, which usually use packed,
+LZMS-compressed streams and may carry the \fI.esd\fR file extension rather than
+\fI.wim\fR. However, such files are not designed for random access, so reading
+data from them when mounted may be very slow. In addition, \fI.esd\fR files
+downloaded directly by the Windows 8 web downloader have encrypted segments, and
+wimlib cannot mount such files until they are first decrypted.
