.SH NAME
@IMAGEX_PROGNAME@-optimize \- Optimize a WIM archive

.SH SYNOPSIS
\fB@IMAGEX_PROGNAME@ optimize\fR \fIWIMFILE\fR [--check] [--recompress]
-
.SH DESCRIPTION
-.PP
\fB@IMAGEX_PROGNAME@ optimize\fR will rebuild the stand-alone WIM \fIWIMFILE\fR. The new
WIM is written to a temporary file, and it is renamed to the original file when
it's ready. This action will remove any holes that have been left as a result
of appending images, so the new WIM may be slightly smaller than the old WIM.
In addition, some errors in the original WIM may be fixed by re-writing it
(although most cannot).

better job than the program that wrote the original file. A side effect of this
is that every stream in the original WIM will be checksummed, so this can help
verify that the WIM is intact (equivalent to applying all the images from it).

+.IP ""
Note: as mentioned in the README, wimlib generally provides a slightly better
XPRESS compression ratio than Microsoft's software, while it generally provides
a slightly worse LZX compression ratio than Microsoft's software. So, you may
not want to specify \fB--recompress\fR when optimizing a LZX-compressed WIM
-created on Windows.

.TP
\fB--threads\fR=\fINUM_THREADS\fR
Number of threads to use for compressing data. Default: autodetect (number of
processors). This parameter is only meaningful when \fB--recompress\fR is also
specified.

.SH NOTES
-
\fB@IMAGEX_PROGNAME@ optimize\fR does not support split WIMs.
