</style><div role="note" class="hatnote navigation-not-searchable">This article is about data object, text, and file comparisons in computing. For other uses, see <a href="Comparison_(disambiguation)" class="mw-disambig" title="Comparison (disambiguation)">Comparison</a>.</div>

<p>Editing documents, program code, or any data always risks introducing errors. Displaying the differences between two or more sets of data, <b>file comparison</b> tools can make computing simpler, and more efficient by focusing on new data and ignoring what did not change. Generically known as a <b>diff</b><sup id="cite_ref-1" class="reference"><a href="#cite_note-1"><span class="cite-bracket">[</span>1<span class="cite-bracket">]</span></a></sup> after the <a href="Unix" title="Unix">Unix</a> <a href="Diff_utility" class="mw-redirect" title="Diff utility"><code>diff</code> utility</a>, there are a range of ways to compare data sources and display the results.

</p><p>Some widely used file comparison programs are <a href="Diff" title="Diff">diff</a>, <a href="Cmp_(Unix)" title="Cmp (Unix)">cmp</a>, <a href="Apple_Developer_Tools#FileMerge" title="Apple Developer Tools">FileMerge</a>, <a href="WinMerge" title="WinMerge">WinMerge</a>, <a href="Beyond_Compare" title="Beyond Compare">Beyond Compare</a>, and <a href="File_Compare" title="File Compare">File Compare</a>.

</p><p>Because understanding changes is important to writers of code or documents, many <a href="Text_editor" title="Text editor">text editors</a> and <a href="Word_processor" title="Word processor">word processors</a> include the functionality necessary to see the changes between different versions of a file or document.

</p>

<div class="mw-heading mw-heading2"><h2 id="Method_types">Method types</h2></div>

<p>The most efficient method of finding differences depends on the source data, and the nature of the changes. One approach is to find the <a href="Longest_common_subsequence_problem" class="mw-redirect" title="Longest common subsequence problem">longest common subsequence</a> between two files, then regard the non-common data as an insertion, or a deletion.

</p><p>In 1978, Paul Heckel published an algorithm that identifies most moved blocks of text.<sup id="cite_ref-2" class="reference"><a href="#cite_note-2"><span class="cite-bracket">[</span>2<span class="cite-bracket">]</span></a></sup> This is used in the <a href="IBM_History_Flow_tool" title="IBM History Flow tool">IBM History Flow tool</a>.<sup id="cite_ref-3" class="reference"><a href="#cite_note-3"><span class="cite-bracket">[</span>3<span class="cite-bracket">]</span></a></sup> Other file comparison programs find block moves.

</p><p>Some specialized file comparison tools find the <a href="Longest_increasing_subsequence" title="Longest increasing subsequence">longest increasing subsequence</a> between two files.<sup id="cite_ref-PatentUS7031972B2_4-0" class="reference"><a href="#cite_note-PatentUS7031972B2-4"><span class="cite-bracket">[</span>4<span class="cite-bracket">]</span></a></sup> The <a href="Rsync" title="Rsync">rsync</a> protocol uses a <a href="Rolling_hash" title="Rolling hash">rolling hash</a> function to compare two files on two distant computers with low communication overhead.

</p><p>File comparison in word processors is typically at the word level, while comparison in most programming tools is at the line level. Byte or character-level comparison is useful in some specialized applications.

</p>

<div class="mw-heading mw-heading2"><h2 id="Display">Display</h2></div>

<p>The optimal way to display the results of a file comparison depends on many factors, including the type of source data. The fixed lines of programming code provide a clear unit of comparison. This does not work with documents, where adding a single word may cause the following lines to wrap differently, but still not change the content.

</p><p>The most popular ways to display changes are either side-by-side, or a consolidating view that highlights data inserts, and deletes. In either side-by-side viewing, <a href="Code_folding" title="Code folding">code folding</a> or <a href="Folding_editor" class="mw-redirect" title="Folding editor">text folding</a>, for the sake of efficiency, the interface may hide portions of the file that did not change and show only the changes.

</p>

<div class="mw-heading mw-heading2"><h2 id="Reasoning">Reasoning</h2></div>

<p>There are various reasons to use comparison tools, and tools themselves use different approaches. To compare binary files, a tool may use byte-level comparison. Comparing <a href="Text_file" title="Text file">text files</a> or <a href="Computer_program" title="Computer program">computer programs</a>, many tools use a side-by-side visual comparison.<sup id="cite_ref-5" class="reference"><a href="#cite_note-5"><span class="cite-bracket">[</span>5<span class="cite-bracket">]</span></a></sup> This gives the user the chance to choose which changes to keep or reject before merging the files into a new version.<sup id="cite_ref-6" class="reference"><a href="#cite_note-6"><span class="cite-bracket">[</span>6<span class="cite-bracket">]</span></a></sup> Or perhaps to keep them both as-is for later reference, through some form of "versioning" control.

</p><p>File comparison is an important, and integral process of <a href="File_synchronization" title="File synchronization">file synchronization</a> and <a href="Backup" title="Backup">backup</a>. In backup methodologies, the issue of <a href="Data_corruption" title="Data corruption">data corruption</a> is important. Rarely is there a warning before corruption occurs, this can make recovery difficult or impossible. Often, the problem is only apparent the next time someone tries to open a file. In this circumstance, a comparison tool can help to isolate the introduction of the problem.<sup id="cite_ref-7" class="reference"><a href="#cite_note-7"><span class="cite-bracket">[</span>7<span class="cite-bracket">]</span></a></sup>

</p>

<div class="mw-heading mw-heading2"><h2 id="Historical_uses">Historical uses</h2></div>

<p>Prior to file comparison, machines existed to compare magnetic tapes or punch cards. The <a href="IBM_519" title="IBM 519">IBM 519 Card Reproducer</a> could determine whether a deck of <a href="Punched_card" title="Punched card">punched cards</a> were equivalent. In 1957, John Van Gardner developed a system to compare the <a href="Check_sum" class="mw-redirect" title="Check sum">check sums</a> of loaded sections of <a href="Fortran" title="Fortran">Fortran</a> programs to <a href="Debugging" title="Debugging">debug</a> compilation problems on the <a href="IBM_704" title="IBM 704">IBM 704</a>.<sup id="cite_ref-8" class="reference"><a href="#cite_note-8"><span class="cite-bracket">[</span>8<span class="cite-bracket">]</span></a></sup>
