\fB@IMAGEX_PROGNAME@ capture\fR (1) for more details.
.TP
+\fB--compress-slow\fR
+Spend even more time compressing the data to achieve a very slightly better
+compression ratio. This currently only has an effect for LZX ("maximum") and
+LZMS ("recovery") compression. This option does not itself set the compression
+format.
+.TP
\fB--pack-streams\fR, \fB--solid\fR
Create a "solid" archive that compresses multiple files together. This can
result in a higher compression ratio, but has disadvantages such as reduced

-Since the WIM format uses single-instancing (streams are content-addressed by
-SHA1 message digests), when an image is exported, only the streams not already
-present in the destination WIM need to be copied. However, a new copy of the
-image's metadata resource always needs to be created.
+\fISingle instancing\fR: The WIM format uses single-instance streams (roughly,
+"files"). When an image is exported, only the streams ("files") not already
+present in the destination WIM will be copied. However, a new copy of the
+image's metadata resource, which describes the full directory structure, will

+\fIESD files\fR: wimlib v1.6.0 and later can export images from version 3584
+WIMs, which usually contain LZMS-compressed solid blocks and may carry the
+\fI.esd\fR file extension rather than \fI.wim\fR. However, \fI.esd\fR files
+downloaded directly by the Windows 8 web downloader have encrypted segments, and
+wimlib cannot export images from such files until they are first decrypted. In
+addition, to ensure the destination archive is created in the original WIM
+format rather than in the newer format, specify \fB--compress\fR=\fImaximum\fR.

Export the second image of 'boot.wim' to the new WIM file 'new.wim':
