32 * \section intro Introduction
34 * wimlib is a C library to read, write, and mount archive files in the Windows
35 * Imaging Format (WIM files). These files are normally created using the @c
36 * imagex.exe utility on Windows, but this library provides a free
37 * implementetion of @c imagex for UNIX-based systems and an API to allow other
38 * programs to read, write, and mount WIM files. wimlib is comparable to
39 * Microsoft's WIMGAPI, but was designed independently and is not a clone of it.
41 * \section format WIM files
43 * A <b>Windows Imaging (WIM)</b> file is an archive. Like some other archive
44 * formats such as ZIP, files in WIM archives may be compressed. WIM archives
45 * support two Microsoft-specific compression formats: @b LZX and @b XPRESS.
46 * Both are based on LZ77 and Huffman encoding, and both are supported by
49 * Unlike ZIP files, WIM files can contain multiple independent toplevel
50 * directory trees known as @a images. While each image has its own metadata,
51 * files are not duplicated for each image; instead, each file is included only
52 * once in the entire WIM. Microsoft did this so that in one WIM file, they
53 * could do things like have 5 different versions of Windows that are almost
56 * Microsoft provides documentation for the WIM file format, XPRESS compression
57 * format, and LZX compression format. The XPRESS documentation is acceptable,
58 * but the LZX documentation is not entirely correct, and the WIM documentation
59 * itself is incomplete.
61 * A WIM file may be either stand-alone or split into multiple parts.
63 * \section ntfs NTFS support
65 * As of version 1.0.0, wimlib supports capturing and applying images directly
66 * to NTFS volumes. This was made possible with the help of libntfs-3g from the
67 * NTFS-3g project. This feature supports capturing and restoring NTFS-specific
68 * data such as security descriptors, alternate data streams, and reparse point
71 * The code for NTFS image capture and image application is complete enough that
72 * it is possible to apply an image from the "install.wim" contained in recent
73 * Windows installation media (Vista, Windows 7, or Windows 8) directly to a
74 * NTFS volume, and then boot Windows from it after preparing the Boot
75 * Configuration Data. In addition, a Windows installation can be captured (or
76 * backed up) into a WIM file, and then re-applied later.
78 * \section winpe Windows PE
80 * A major use for this library is to create customized images of Windows PE, the
81 * Windows Preinstallation Environment, without having to rely on Windows. Windows
82 * PE is a lightweight version of Windows that can run entirely from memory and can
83 * be used to install Windows from local media or a network drive or perform
84 * maintenance. Windows PE is the operating system that runs when you boot from
85 * the Windows installation media.
87 * You can find Windows PE on the installation DVD for Windows Vista, Windows 7,
88 * or Windows 8, in the file @c sources/boot.wim. Windows PE can also be found
89 * in the Windows Automated Installation Kit (WAIK), which is free to download
90 * from Microsoft, inside the @c WinPE.cab file, which you can extract if you
91 * install either the @c cabextract or @c p7zip programs.
93 * In addition, Windows installations and recovery partitions frequently contain a
94 * WIM containing an image of the Windows Recovery Environment, which is similar to
97 * \section starting Getting Started
99 * wimlib uses the GNU autotools, so it should be easy to install with
100 * <code>configure && make && sudo make install</code>; however, please see the
101 * README for more information about installing it. To use wimlib in a program
102 * after installing it, include @c wimlib.h and link your program with @c -lwim.
104 * wimlib wraps up a WIM file in an opaque ::WIMStruct structure. A ::WIMStruct
105 * may represent either a stand-alone WIM or one part of a split WIM.
107 * All functions in wimlib's public API are prefixed with @c wimlib. Most
108 * return an integer error code on failure. Use wimlib_get_error_string() to
109 * get a string that describes an error code. wimlib also can print error
110 * messages itself when an error happens, and these may be more informative than
111 * the error code; to enable this, call wimlib_set_print_errors(). Please note
112 * that this is for convenience only, and some errors can occur without a
113 * message being printed.
115 * wimlib is thread-safe as long as different ::WIMStruct's are used, except for
116 * the fact that wimlib_set_print_errors() and wimlib_set_memory_allocator()
117 * both apply globally.
119 * To open an existing WIM, use wimlib_open_wim().
121 * To create a new WIM that initially contains no images, use
122 * wimlib_create_new_wim().
124 * To add an image to a WIM file from a directory tree on your filesystem, call
125 * wimlib_add_image(). This can be done with a ::WIMStruct gotten from
126 * wimlib_open_wim() or from wimlib_create_new_wim(). wimlib_add_image() can
127 * also capture a WIM image directly from a NTFS volume if you provide the
128 * ::WIMLIB_ADD_IMAGE_FLAG_NTFS flag, provided that wimlib was not compiled with
129 * the <code>--without-ntfs-3g</code> flag.
131 * To extract an image from a WIM file, call wimlib_extract_image(). You may
132 * extract an image either to a directory or directly to a NTFS volume, the
133 * latter of which will preserve NTFS-specific data such as security
136 * wimlib supports mounting WIM files either read-only or read-write. Mounting
137 * is done using wimlib_mount_image() and unmounting is done using
138 * wimlib_unmount_image(). Mounting can be done without root privileges because
139 * it is implemented using FUSE (Filesystem in Userspace). If wimlib is
140 * compiled with the <code>--without-fuse</code> flag, these functions will be
141 * available but will fail with ::WIMLIB_ERR_UNSUPPORTED.
143 * After creating or modifying a WIM file, you can write it to a file using
144 * wimlib_write(). Alternatively, if the WIM was originally read from a file
145 * (using wimlib_open_wim() rather than wimlib_create_new_wim()), you can use
146 * wimlib_overwrite() to overwrite the original file.
148 * Please note: merely by calling wimlib_add_image() or many of the other
149 * functions in this library that operate on ::WIMStruct's, you are @b not
150 * modifying the WIM file on disk. Changes are not saved until you explicitly
151 * call wimlib_write() or wimlib_overwrite().
153 * After you are done with the WIM file, use wimlib_free() to free all memory
154 * associated with a ::WIMStruct and close all files associated with it.
156 * A number of functions take a pointer to a progress function of type
157 * ::wimlib_progress_func_t. This function will be called periodically during
158 * the WIM operation(s) to report on the progress of the operation (for example,
159 * how many bytes have been written so far).
161 * \section imagex imagex
163 * wimlib comes with a command-line interface, the @b imagex program. It is
164 * documented with man pages. See its source code (@c programs/imagex.c in
165 * wimlib's source tree) for an example of how to use wimlib in your program.
167 * \section mkwinpeimg mkwinpeimg
169 * wimlib also comes with the <b>mkwinpeimg</b> script, which is documented in a
172 * \section Limitations
174 * While wimlib supports the main features of WIM files, wimlib currently has
175 * the following limitations:
176 * - wimlib cannot be used on MS-Windows.
177 * - There is no way to add, remove, modify, or extract specific files in a WIM
178 * without mounting it, other than by adding, removing, or extracting an
179 * entire image. The FUSE mount feature should be used for this purpose.
180 * - Currently, Microsoft's @a image.exe can create slightly smaller WIM files
181 * than wimlib when using maximum (LZX) compression because it knows how to
182 * split up LZX compressed blocks, which is not yet implemented in wimlib.
183 * - wimlib is experimental and likely contains bugs; use Microsoft's @a
184 * imagex.exe if you want to make sure your WIM files are made "correctly".
185 * - The old WIM format from Vista pre-releases is not supported.
186 * - Compressed resource chunk sizes other than 32768 are not supported,
187 * although this doesn't seem to be a problem because the chunk size always
188 * seems to be this value.
189 * - wimlib does not provide a clone of the @b PEImg tool that allows you to
190 * make certain Windows-specific modifications to a Windows PE image, such as
191 * adding a driver or Windows component. Such a tool could conceivably be
192 * implemented on top of wimlib, although it likely would be hard to implement
193 * because it would have to do very Windows-specific things such as
194 * manipulating the driver store. wimlib does provide the @b mkwinpeimg
195 * script for a similar purpose, however. With regards to adding drivers to
196 * Windows PE, you have the option of putting them anywhere in the Windows PE
197 * image, then loading them after boot using @b drvload.exe.

1546 * The second way to overwrite a WIM is by appending to the end of it and
1547 * overwriting the header. This can be much faster than a full rebuild, but it

1552 * integrity were. This is done so that the WIM remains valid even if the
1553 * operation is aborted mid-write. The WIM header is only overwritten at the
1554 * very last moment, and up until that point the WIM will be seen as the old
