<h1>Applications</h1>
<p>Before diving into all the applications that come with Haiku, let's have a more detailed look at how to install and uninstall programs you downloaded somewhere, for example from a site mentioned on the <ahref="../../welcome/welcome_pt_PT.html#software">Welcome</a> page.</p>
<divclass="box-info">You should only unpack/install archives within Haiku. If you extract a package under Linux or Windows, for example, and just copy the folder over to Haiku later, all the vital attributes are stripped, because those operating systems don't normally handle meta data.</div>
<p>Haiku software always comes as an archive. Most of the time it's a ZIP, some old BeOS packages come in Software Valet's PKG format. Software Valet was able to automatically execute installation scripts, so after double-clicking you just select a destination folder and everything's taken care of.<br/>
If it's a ZIP archive, double-clicking opens <spanclass="app">Expander</span> where you also set the destination and unpack it. As explained in the topic <ahref="filesystem-layout.html">Filesystem layout</a>, that destination is either</p>
<tr><td><spanclass="path">/boot/common/apps/</span></td><td></td><td> for applications available to every user</td></tr>
<tr><td><spanclass="path">/boot/home/apps/</span></td><td></td><td> for applications only available to yourself</td></tr>
</table>
<p>This distinction will only become relevant once Haiku gets multi-user support, of course.</p>
<p>Once the archive is unpacked, you should have a look into the newly created folder. Often you find ReadMe files or other documentation of interest.</p>
<p>Some programs need further configurations. For example, <ahref="tracker-add-ons.html">Tracker Add-Ons</a>, <ahref="preferences/datatranslations.html">Translators</a> or other system enhancing components have to be put into the right folders. Either you'll find a little script file (often with the suffix <spanclass="cli">.sh</span>) like <spanclass="cli">install</span> that you simply double click to have all taken care of.<br/>
Sometimes you'll find folders that link to the correct destination named "<spanclass="cli">drag [filename] here...</span>". So, you simply follow that instruction and you're done.</p>
<p>Most of the time, however, nothing of the sort is necessary and you're done after unpacking.<br/>
Topics <ahref="deskbar.html">Deskbar</a> or <ahref="desktop-applets/launchbox.html">LaunchBox</a> describe how to add shortcuts to your newly installed application.</p>
<p>If the installation was done with an install script, chances are, there's an uninstall script as well. In that case, double-click it and you're done.<br/>
Otherwise, uninstalling is simply done by deleting the application's folder.</p>
<p>This, of course, leaves back possible configuration files in your <spanclass="path">~/config/settings</span> folder. This may be on purpose, if you want to keep those settings in case you'll install the program again in the future. Also, when the installation involved those "<spanclass="cli">drag [filename] here...</span>" folders, those files are also left behind.</p>
<p>One method to quickly get to all the app's files is to do a quick query for a significant part of the application's name. This will reveal the app's binary, its installation folder and its settings as well as possible links in the Deskbar etc. Simply select all relevant files and delete them.</p>
<p>Haiku comes with a set of mostly small but essential applications. You'll find all of them at <spanclass="path">/boot/system/apps/</span> or <spanclass="path">/boot/common/apps/</span>. Applications that are not usually launched by a double-click on a data file (e.g. ShowImage for image files) can be found in the <spanclass="menu">Applications</span> menu of the Deskbar.</p>
<p>Besides the normal commandline tools coming with the bash shell or are necessary to be POSIX compliant, there are a few Haiku-specific commandline applications worth mentioning. These commands are often useful for scripting purposes, see also topic <ahref="bash-scripting.html">Bash and Scripting</a>.</p>

<p>Besides the above listed programs, which are all maintained by the Haiku project, there are a few essential applications bundled in a standard Haiku system. Bugs and feature requests for those have to be filed with the particular maintainer.</p>
