<section id="how-does-the-duplicate-search-work">
<h1>Hoe werkt het zoeken naar duplicaten?<a class="headerlink" href="#how-does-the-duplicate-search-work" title="Link to this heading">¶</a></h1>
<p>Het zoeken naar duplicaten maakt deel uit van TreeSize Bestand Zoeken, dat kan worden gestart vanaf het tabblad “Start” in de hoofdmodule, of via de aparte snelkoppeling in je Windows Start-menu.</p>
<section id="step-1-activate-the-duplicate-search-and-select-a-search-path">
<h2>Stap 1: Activeer de duplicaatzoekfunctie en selecteer een zoekpad<a class="headerlink" href="#step-1-activate-the-duplicate-search-and-select-a-search-path" title="Link to this heading">¶</a></h2>
<p>Om een duplicaatzoekopdracht in te stellen, schakelt u eerst het selectievakje “Dubbele bestanden” aan de linkerkant in.</p>
<p>Gebruik het paneel boven de zoekresultatenlijst om de schijf of het pad te selecteren dat u wilt doorzoeken. U kunt aanvullende informatie vinden over hoe u een zoekpad instelt in dit hoofdstuk.</p>
<p>Het is ook mogelijk om naar duplicaten te zoeken op meerdere schijven of paden.</p>
</section>
<section id="step-2-select-a-comparison-method-and-minimum-file-size">
<h2>Stap 2: Selecteer een vergelijkingsmethode en minimale bestandsgrootte<a class="headerlink" href="#step-2-select-a-comparison-method-and-minimum-file-size" title="Link to this heading">¶</a></h2>
<p>De volgende stap is om het mechanisme te selecteren dat moet worden gebruikt om bestanden met elkaar te vergelijken. U kunt de bestanden alleen op hun naam vergelijken, of een combinatie van naam, grootte en datum.</p>
<p>De meest nauwkeurige methode is echter de checksum. Een duplicaatzoekopdracht die gebruikmaakt van bestandschecksums is langzamer, maar zal veel nauwkeuriger zijn, aangezien de werkelijke inhoud van de bestanden wordt gebruikt voor de berekening.</p>
<p>Om dit te doen, selecteert u de optie “Bestandsinhoud” in het menu, onder “Dubbele Bestanden > Vergelijkingsmethode”.</p>
<p>Het is ook aan te raden om een minimale grootte voor de zoekopdracht te definiëren, zodat kleine bestanden snel kunnen worden overgeslagen. Kleinere bestanden dragen niet veel bij aan de totale grootte op de schijf, dus hun verwijdering zou niet veel ruimte opleveren.</p>
<p>U kunt ook andere filters definiëren, zoals “Bestandstype”, wat kan helpen om de duplicaatzoekopdracht te versnellen door alleen op een specifieke subset van bestanden te draaien.</p>
</section>
<section id="step-3-run-the-search">
<h2>Stap 3: Voer de zoekopdracht uit<a class="headerlink" href="#step-3-run-the-search" title="Link to this heading">¶</a></h2>
<p>Zodra u alle noodzakelijke parameters hebt geconfigureerd, kunt u de zoekopdracht uitvoeren en de resultaten analyseren.</p>
<p>Elk duplicaat wordt onder een groep in de resultatenlijst gerangschikt.</p>
<p>De volgende screenshot toont een voorbeeldconfiguratie zoals hierboven vermeld en toont de resultaten van de zoekopdracht:</p>

<section id="step-4-analyze-the-results-and-perform-the-cleanup-operation">
<h2>Stap 4: Analyseer de resultaten en verwijder overbodige bestanden<a class="headerlink" href="#step-4-analyze-the-results-and-perform-the-cleanup-operation" title="Link to this heading">¶</a></h2>
<section id="deduplication">
<h3>Ontdubbelen<a class="headerlink" href="#deduplication" title="Link to this heading">¶</a></h3>
<p>De gemakkelijkste manier om schijfruimte te winnen met de duplicaatzoekopdracht is door een <a class="reference internal" href="deduplication.html#deduplication"><span class="std std-ref">Hoe werkt het ontdubbelen?</span></a> uit te voeren.</p>
<p>Vink gewoon de bestanden aan die u wilt ontdubbelen en selecteer “Ontdubbel” in het lint.</p>
<p>TreeSize vervangt alle bestanden behalve het nieuwste bestand met NTFS-hardlinks. Na het ontdubbelen zullen de kopieën geen ruimte meer op de schijf innemen.</p>
</section>
<section id="delete-archive">
<h3>Verwijderen/Archiveren<a class="headerlink" href="#delete-archive" title="Link to this heading">¶</a></h3>
<p>Een andere manier om ruimte vrij te maken, is door de dubbele bestanden van de schijf te verwijderen.</p>
<p>In tegenstelling tot het ontdubbelen, zullen de dubbele bestanden volledig van de schijf worden verwijderd. Er zal geen overgebleven link naar de originele gegevens zijn.</p>
<p>Dit vereist ook dat u handmatig de bestanden selecteert die moeten worden verwijderd.</p>
<p>TreeSize biedt echter een verscheidenheid aan functies die u helpen alleen de dubbele bestanden te selecteren, zodat er altijd één “origineel” bestand overblijft.</p>
<p>In het lint van de zoekopdracht voor dubbelen vindt u de categorie “Lijstacties”, die functionaliteit biedt voor het controleren van “Alleen maar de …” nieuwste, oudste, eerste of laatste bestand van elke dubbele groep.</p>
<p>Dit stelt u in staat om alle bestanden van een dubbele groep te selecteren, maar één bestand niet aan te vinken (het bestand dat niet zal worden verwijderd).</p>
<p>Als u een meer aangepaste selectie wilt maken, zoals “alleen bestanden van schijf <code class="docutils literal notranslate"><span class="pre">G:\"</span></code>, kunt u de dialoog “Controleren of” gebruiken om een aangepast selectiemodel te maken.</p>
<p>Hiervoor kan het ook nuttig zijn om “Zorg ervoor dat er één niet aangevinkt bestand per groep is” te selecteren. Als deze optie is ingeschakeld, zorgt TreeSize ervoor dat er onder alle omstandigheden één bestand per dubbele groep niet is aangevinkt. Dit voorkomt gevallen waarin per ongeluk alle bestanden van een groep zijn aangevinkt, zodat er geen origineel bestand overblijft na de verwijderingsoperatie.</p>
<p>Nadat u de bestanden die moeten worden verwijderd hebt aangevinkt, klikt u op “Verwijder items” in het lint om het verwijderingsdialoogvenster te activeren (<a class="reference internal" href="move_checked_files.html#move-checked-files"><span class="std std-ref">Verplaats geselecteerde bestanden</span></a>), waar u kunt selecteren welke operatie moet worden uitgevoerd.</p>
<p>U kunt de bestanden ofwel verwijderen, of ze naar een andere locatie verplaatsen. In beide gevallen kunt u een logbestand van de operatie aanmaken, dat een samenvatting van de operatie biedt en u in staat stelt de resultaten te verifiëren.</p>
<p>Klik ten slotte op “Uitvoeren” om de operatie te starten.</p>
