To <span class="emphasis"><em>bulk rename</em></span> files means to rename multiple files at once using some criterion, that applies to atleast
3
one of the files. <strong class="application"><code>Thunar</code></strong> includes a bulk renamer, which can be run separately using the command
4
<span class="command"><strong>Thunar -B</strong></span> or from within <strong class="application"><code>Thunar</code></strong> by selecting two or more files in the main area
5
and pressing <span class="keycap"><strong>F2</strong></span> or choosing
6
<span class="guimenu"><strong>Edit</strong></span> → <span class="guimenuitem"><strong>Rename...</strong></span> from the main menu.

8
The <span class="emphasis"><em>Bulk Renamers</em></span> can be applied to the name of the files, the suffix of the files or both to the
9
name and the suffix of the files. <strong class="application"><code>Thunar</code></strong> currently supports the following <span class="emphasis"><em>Bulk

12
Additional <span class="emphasis"><em>Bulk Renamers</em></span> may be installed as plugins for <strong class="application"><code>Thunar</code></strong>. Check
13
the <a class="ulink" href="http://thunar.xfce.org/plugins.html" target="_top">Thunar Plugins</a> website for currently available
14
extensions. The <a class="ulink" href="http://thunar.xfce.org/pwiki/documentation/bulk_renamer" target="_top">Thunar Project Wiki</a>

contains further details about this feature. Feel free to add more information to the Wiki.

17
While the Thunar file manager does a good job at abstracting the details of the underlying file system, so the user
18
does not need to care about them, it is sometimes useful to understand the basic concepts to get the whole picture.
19
This section tries to give a brief introduction to the concepts of the UNIX file system, which is used today by all
20
incarnations of UNIX, including Linux.
21
</p><div class="sect3" title="Folders and Paths"><div class="titlepage"><div><div><h4 class="title"><a name="folders-and-paths"></a>Folders and Paths</h4></div></div></div><p>
22
In a UNIX file system all folders are arranged in a simple inverted tree structure descending and branching down
23
from a single top level folder, which is called the <span class="emphasis"><em>root directory</em></span> (the term
24
<span class="emphasis"><em>directory</em></span> is often used instead of <span class="emphasis"><em>folder</em></span>) and displayed as
25
<span class="guilabel"><strong>File System</strong></span> in Thunar. This means that you can get from any folder to any other by going
26
up the tree until you reach a common point, then down the tree through the appropriate subfolders until you reach
29
The position of any file or folder in the tree can be described by its <span class="emphasis"><em>path</em></span>. The path is the
30
list of folders you would have to descend through to get to the target folder or file, starting from the top level
31
folder. For example <code class="filename">/home/luke</code> is the subfolder <code class="filename">luke</code> of the subfolder <code class="filename">home</code> of the top level folder,
32
and <code class="filename">/home/luke/myfile.txt</code> is the file <code class="filename">myfile.txt</code> in that subfolder. The
33
leading <code class="filename">/</code> in these paths represents the top level folder.
35
Every user has their own folder to hold their personal files and settings. This folder is called the <span class="emphasis"><em>home
36
directory</em></span> and is displayed in Thunar as special icon with the users login name. The folder is similar to
37
the <span class="guilabel"><strong>My Files</strong></span> folder known from Windows. The <span class="emphasis"><em>home directories</em></span> of the various
38
users in a system are usually located below the <code class="filename">/home</code> folder. For example
39
<code class="filename">/home/luke</code> would be the home directory of the user with the login name
40
<code class="filename">luke</code>, while <code class="filename">/home/jane</code> would be
41
the home directory for the user with the login name <code class="filename">jane</code>.

You may have already heard that everything is a file in UNIX. This is true for most objects present in UNIX systems
44
today. In fact even devices are represented as a special files. While this may not make sense at first sight, it is
45
one of the strengths of UNIX and its derivates, and has helped it to maintain a simple core over the years where other
46
operating systems had to introduce new concepts for every new technology.
48
These are the four most important types of files in the UNIX file system.
49
</p><div class="sect4" title="Ordinary Files"><div class="titlepage"><div><div><h5 class="title"><a name="file-types-ordinary-files"></a>Ordinary Files</h5></div></div></div><p>
50
An ordinary file may contain text, a program or other data. This includes image files, audio files, office documents
51
and video files. The term <span class="emphasis"><em>file</em></span> is often used to refer to an ordinary file.
52
</p></div><div class="sect4" title="Folder Files"><div class="titlepage"><div><div><h5 class="title"><a name="file-types-folder-files"></a>Folder Files</h5></div></div></div><p>
53
Folders are also files in the UNIX file system. To be exact a folder is a special file, which contains a
54
mapping of file names to file references for every file contained within this folder.
55
</p></div><div class="sect4" title="Symbolic Link Files"><div class="titlepage"><div><div><h5 class="title"><a name="file-types-symbolic-link-files"></a>Symbolic Link Files</h5></div></div></div><p>
56
A Symbolic link (often called a <span class="emphasis"><em>symlink</em></span>) is a special file that contains a path to
57
another file in the file system. Symbolic link files therefore do not contain any useful information
58
themselves, but just refer to other files.
59
</p></div><div class="sect4" title="Device Files"><div class="titlepage"><div><div><h5 class="title"><a name="file-types-device-files"></a>Device Files</h5></div></div></div><p>
60
As mentioned earlier (most) devices are also accessed through the file system. These special device files are
61
usually located in the <code class="filename">/dev</code> folder. For example the special file
62
<code class="filename">/dev/hda</code> represents the first IDE disk on Linux.
