.SH NAME
wimlib-imagex-apply \- Extract one image, or all images, from a WIM archive
.SH SYNOPSIS
.IP \[bu]
All names of all files, including names in the Win32 namespace, DOS namespace,
Win32+DOS namespace, and POSIX namespace. This includes hard links.
+.IP \[bu]
+Object IDs.
.PP
However, there are also several known limitations of the NTFS volume extraction
mode:

Encrypted files will not be extracted.
.IP \[bu]
-wimlib v1.7.0 and later: Sparse file attributes will not be extracted (same
-behavior as ImageX/DISM/WIMGAPI). wimlib v1.6.2 and earlier: Although sparse
-file attributes will be applied, the full data will be extracted to each sparse
-file, so extracted "sparse" files may not actually contain any sparse regions.
+Sparse file attributes will not be extracted.
.PP
Regardless, since almost all information from the WIM image is restored in this
mode, it is possible (and fully supported) to restore an image of an actual
set if the user does not have permission to set them, which can be a problem if
\fBwimlib-imagex\fR is run as a non-Administrator.
.IP \[bu]

considered an error condition.

above not being supported by the target filesystem.

Since encrypted files (with FILE_ATTRIBUTE_ENCRYPTED) are not stored in
plaintext in the WIM image, \fBwimlib-imagex\fR cannot restore encrypted
files to filesystems not supporting encryption. Therefore, on such filesystems,
concatenated together on standard input. They can be provided in any order,
with the exception of the first part, which must be first.

+Exclusions are handled in the same way as with the \fB--wimboot\fR option.

+files matching any of the patterns in this section will not be compressed.
+In addition, wimlib has a hardcoded list of files for which it knows, for
