<h1>Hvordan fungerer duplikatsøgningen?<a class="headerlink" href="#how-does-the-duplicate-search-work" title="Link to this heading">¶</a></h1>
<p>Duplikatsøgningen er en del af TreeSize File Search, som kan startes fra fanen »Home« i hovedmodulet eller via den separate genvej i din Windows Start-menu.</p>
<section id="step-1-activate-the-duplicate-search-and-select-a-search-path">
<h2>Trin 1: Aktivér søgningen efter dubletter og vælg en søgesti<a class="headerlink" href="#step-1-activate-the-duplicate-search-and-select-a-search-path" title="Link to this heading">¶</a></h2>
<p>For at opsætte en søgning efter dubletter, skal du først aktivere afkrydsningsfeltet »Duplicate Files« på venstre side.</p>
<p>Brug panelet over søgeresultatliste til at vælge det drev eller den sti, du ønsker at søge i. Du kan finde yderligere information om, hvordan du opsætter en søgesti i dette kapitel.</p>
<p>Det er også muligt at søge efter dubletter på tværs af flere drev eller stier.</p>
</section>
<section id="step-2-select-a-comparison-method-and-minimum-file-size">
<h2>Trin 2: Vælg en sammenligningsmetode og minimum filstørrelse<a class="headerlink" href="#step-2-select-a-comparison-method-and-minimum-file-size" title="Link to this heading">¶</a></h2>
<p>Det næste skridt er at vælge den mekanisme, der skal bruges til at sammenligne filer med hinanden. Du kan sammenligne filerne kun efter deres navn, eller en kombination af navn, størrelse og dato.</p>
<p>Den mest nøjagtige metode er dog checksum. En søgning efter dubletter, der bruger filchecksums, er langsommere, men vil være meget mere præcis, da det faktiske indhold af filerne bruges til beregningen.</p>
<p>For at gøre dette, vælg »File Content« indstillingen fra ribbon-menuen under »Duplicate Files > Comparison Method«.</p>
<p>Det anbefales også at definere en minimumsstørrelse for søgningen, så små filer hurtigt kan springes over. Mindre filer bidrager ikke meget til den samlede størrelse på drevet, så deres fjernelse ville ikke give meget plads.</p>
<p>Du kan også definere andre filtre, såsom »File Type«, som kan hjælpe med at fremskynde søgningen efter dubletter ved kun at køre på et specifikt udvalg af filer.</p>
</section>
<section id="step-3-run-the-search">
<h2>Trin 3: Kør søgningen<a class="headerlink" href="#step-3-run-the-search" title="Link to this heading">¶</a></h2>
<p>Når du har konfigureret alle nødvendige parametre, kan du køre søgningen og analysere resultaterne.</p>
<p>Hver forekomst af en dublet er arrangeret under en gruppe i resultatlisten.</p>
<p>Det følgende screenshot viser et eksempel på konfigurationen som nævnt ovenfor og viser resultaterne af søgningen:</p>

<h2>Trin 4: Analyser resultaterne og udfør oprydningsoperationen<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>Deduplicering<a class="headerlink" href="#deduplication" title="Link to this heading">¶</a></h3>
<p>Den nemmeste måde at få diskplads ved hjælp af søgningen efter dubletter er at udføre en <a class="reference internal" href="deduplication.html#deduplication"><span class="std std-ref">Hvordan fungerer deduplikeringsprocessen?</span></a>.</p>
<p>Marker blot de filer, du ønsker at deduplicere, og vælg »Deduplicate« fra ribbon-menuen.</p>
<p>TreeSize vil erstatte alle undtagen den nyeste fil med NTFS-hardlinks. Efter dedupliceringen vil kopierne ikke længere optage plads på drevet.</p>
</section>
<section id="delete-archive">
<h3>Slet/Arkiver<a class="headerlink" href="#delete-archive" title="Link to this heading">¶</a></h3>
<p>En anden måde at frigøre plads på er at slette de duplikatfiler, der findes på disken.</p>
<p>I modsætning til deduplikeringsmetoden vil de duplikatfiler blive fjernet helt fra disken. Der vil ikke være nogen tilbageværende forbindelse til de originale data.</p>
<p>Dette kræver også, at du manuelt vælger de filer, der skal fjernes.</p>
<p>Dog tilbyder TreeSize en række funktioner, der hjælper dig med kun at vælge duplikatfilerne, så én »original« fil altid forbliver.</p>
<p>I ribbon-menuen for duplikatsøgning kan du finde kategorien »Listehandlinger«, som giver funktionalitet til at kontrollere »Alle undtagen de …« nyeste, ældste, første eller sidste fil i hver duplikatgruppe.</p>
<p>Dette giver dig mulighed for at vælge alle filer i en duplikatgruppe, men lade én fil være ikke-udvalgt (den fil, der ikke vil blive slettet).</p>
<p>Hvis du ønsker at lave et mere tilpasset valg, såsom »kun filer fra drev <code class="docutils literal notranslate"><span class="pre">G:\"</span></code>, kan du bruge dialogboksen »Kontroller om« til at oprette et tilpasset valgsmønster.</p>
<p>Til dette formål kan det også være nyttigt at vælge »Sikre én ikke-udvalgt fil pr. gruppe«. Hvis denne mulighed er aktiveret, vil TreeSize sikre, at én fil pr. duplikatgruppe forbliver ikke-udvalgt under alle omstændigheder. Dette forhindrer tilfælde, hvor alle filer i en gruppe ved et uheld blev valgt, så der ikke ville være nogen originalfil tilbage efter sletningsoperationen.</p>
<p>Efter at have kontrolleret de filer, der skal slettes, skal du klikke på »Slet elementer« i ribbon-menuen for at udløse sletningsdialogen (<a class="reference internal" href="move_checked_files.html#move-checked-files"><span class="std std-ref">Flyt markerede filer</span></a>), hvor du kan vælge, hvilken operation der skal udføres.</p>
<p>Du kan enten slette filerne eller flytte dem til en anden placering. I begge tilfælde kan du oprette en logfil over operationen, som giver et resumé af operationen og giver dig mulighed for at verificere resultaterne.</p>
<p>Endelig skal du klikke på »Udfør« for at starte operationen.</p>
