<h2><a class="toc-backref" href="#id2">What is dupeGuru?</a><a class="headerlink" href="#what-is-dupeguru" title="Permalink to this headline"></a></h2>
<p>dupeGuru is a tool to find duplicate files on your computer. It has three operational modes:
Standard, Music and Picture. Each mode has its own specialized preferences.</p>
<p>Each mode has multiple scan types, such as filename, contents, tags. Some scan types feature
advanced fuzzy matching algorithm, allowing you to find duplicates that other more rigid duplicate
scanners cant.</p>

<div class="section" id="what-makes-it-special">
<h2><a class="toc-backref" href="#id3">What makes it special?</a><a class="headerlink" href="#what-makes-it-special" title="Permalink to this headline"></a></h2>
<p>Its mostly about customizability. Theres a lot of scanning options that allow you to get the
type of results youre really looking for.</p>

<div class="section" id="how-safe-is-it-to-use-dupeguru">
<h2><a class="toc-backref" href="#id4">How safe is it to use dupeGuru?</a><a class="headerlink" href="#how-safe-is-it-to-use-dupeguru" title="Permalink to this headline"></a></h2>
<p>Very safe. dupeGuru has been designed to make sure you dont delete files you didnt mean to delete.
First, there is the reference folder system that lets you define folders where you absolutely
<strong>dont</strong> want dupeGuru to let you delete files there, and then there is the group reference system
that makes sure that you will <strong>always</strong> keep at least one member of the duplicate group.</p>

<p>dupeGuru is hosted on <a class="reference external" href="https://github.com/hsoft/dupeguru">Github</a> and its also where issues are tracked. The best way to report a
bug or suggest a feature is to sign up on Github and <a class="reference external" href="https://github.com/hsoft/dupeguru/wiki/issue-labels">open an issue</a>.</p>

<p>You cannot mark the reference (The first file) of a duplicate group. However, what you can do is to
promote a duplicate file to reference. Thus, if a file you want to mark is reference, select a
duplicate file in the group that you want to promote to reference, and click on
<strong>Actions&gt;Make Selected into Reference</strong>. If the reference file is from a reference folder
(filename written in blue letters), you cannot remove it from the reference position.</p>

<h2><a class="toc-backref" href="#id7">I have a folder from which I really dont want to delete files.</a><a class="headerlink" href="#i-have-a-folder-from-which-i-really-don-t-want-to-delete-files" title="Permalink to this headline"></a></h2>
<p>If you want to be sure that dupeGuru will never delete file from a particular folder, make sure to
set its state to <strong>Reference</strong> at <a class="reference internal" href="folders.html"><span class="doc">Folder Selection</span></a>.</p>

<p>In some cases, some matches are not included in the final results for security reasons. Let me use
an example. We have 3 file: A, B and C. We scan them using a low filter hardness. The scanner
determines that A matches with B, A matches with C, but B does <strong>not</strong> match with C. Here, dupeGuru
has kind of a problem. It cannot create a duplicate group with A, B and C in it because not all
files in the group would match together. It could create 2 groups: one A-B group and then one A-C
group, but it will not, for security reasons. Lets think about it: If B doesnt match with C, it
probably means that either B, C or both are not actually duplicates. If there would be 2 groups (A-B
and A-C), you would end up delete both B and C. And if one of them is not a duplicate, that is
really not what you want to do, right? So what dupeGuru does in a case like this is to discard the
A-C match (and adds a notice in the status bar). Thus, if you delete B and re-run a scan, you will
have a A-C match in your next results.</p>

<p>If your comparison threshold is low enough, you will probably end up with live and remix
versions of your songs in your results. Theres nothing you can do to prevent that, but theres
something you can do to easily remove them from your results after the scan: post-scan
filtering. If, for example, you want to remove every song with anything inside square brackets

<li>Type “[*]” in the “Filter” field in the top-right corner of the result window.</li>

<p>This slider is only relevant for scan types that support “fuzziness”. Many scan types, such as the
“Contents” type, only support exact matches. When these types are selected, the slider is disabled.</p>
<p>On some OS, the fact that its disabled is harder to see than on others, but if you cant move the
slider, it means that this preference is irrelevant in your current scan type.</p>

<p>Most of the time, the reason why dupeGuru cant send files to Trash is because of file permissions.
You need <em>write</em> permissions on files you want to send to Trash.</p>
<p>If dupeGuru still gives you troubles after fixing your permissions, try enabling the “Directly
delete files” option that is offered to you when you activate Send to Trash. This will not send
files to the Trash, but delete them immediately. In some cases, for example on network storage
(NAS), this has been known to work when normal deletion didnt.</p>
<p>If this fail, <a class="reference external" href="https://forum.hardcoded.net/">HS forums</a> might be of some help.</p>

<h2><a class="toc-backref" href="#id18">Why is Picture modes contents scan so slow?</a><a class="headerlink" href="#why-is-picture-mode-s-contents-scan-so-slow" title="Permalink to this headline"></a></h2>
<p>This scanning method is very different from methods. It can detect duplicate photos even if they
are not exactly the same. This very cool capability has a cost: time. Every picture has to be
individually and fuzzily matched to all others, and this takes a lot of CPU power.</p>
<p>If all you need to find is exact duplicates, just use the standard mode of dupeGuru with the
Contents scan method. If your photos have EXIF tags, you can also try the “EXIF” scan method which
is much faster.</p>
