    <p>Why are you using <em>editors</em> to just <em>look</em> at a (large) file?</p> <p>Under *nix or <a href="http://en.wikipedia.org/wiki/Cygwin" rel="noreferrer">Cygwin</a>, just use less ("less is more", only better, since you can back up). Searching and navigating under <a href="http://linux.die.net/man/1/less" rel="noreferrer">less</a> is very similar to <a href="http://en.wikipedia.org/wiki/Vim_%28text_editor%29" rel="noreferrer">Vim</a>, but there is no swap file and little RAM used.</p> <p>There is a native <a href="http://en.wikipedia.org/wiki/Windows_API" rel="noreferrer">Win32</a> port of GNU "less". See the comment below.</p> <p>Piggybacking off of some of the comments below, Perl's ".." (range flip/flop) operator makes a nice selection mechanism to limit the crud you have to wade through, as well.</p> <p>For example:</p> <pre><code>$ perl -n -e 'print if ( 1000000 .. 2000000)' humongo.txt | less </code></pre> <p>(start at line 1 million and stop at line 2 million, sift the output manually in "less")</p> <pre><code>$ perl -n -e 'print if ( /interesting regex/ .. /boring regex/)' humongo.txt | less </code></pre> <p>(start when the "interesting regular expression" finds something, stop when the "boring regular expression" find the end of an interesting block -- may find multiple blocks, sift the output...)</p> <p>Finally, 100&nbsp;MB isn't too big. 3&nbsp;GB is getting kind of big. I used to work at a print &amp; mail facility that created about 2 % of U.S. first class mail. One of the systems for which I was the tech lead accounted for about 15+ % of the pieces of mail. We had some big files to debug here and there.</p> <p>Community Wiki Suggestions:</p> <p>Use LogParser to look at the file:</p> <pre><code>logparser.exe -i:textline -o:tsv "select Index, Text from 'c:\path\to\file.log' where line &gt; 1000 and line &lt; 2000" logparser.exe -i:textline -o:tsv "select Index, Text from 'c:\path\to\file.log' where line like '%pattern%'" </code></pre>

    1. CO+1, I recently had some really huge xml files (+1 gigabyte) that I needed to look at. I'm on windows and both vim, emacs, notepad++ and several other editors completely choked on the file to the point where my system almost became unusable when trying to open the file. After a while I realized how unnecessary it was to actually attempt to open the file in an -editor- when I just needed to -view- it. Using cygwin (and some clever grep/less/sed-magic) I easily found the part I was interested in and could read it without any hassle.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
