			<content:encoded><![CDATA[<p>Here&#8217;s my reasonably quick and free way to compare the files in a folder.  I&#8217;ve assumed a bit of computer knowledge, mostly, because I don&#8217;t have time to fill in the many little details.</p>
<p>Get a copy of WinMerge from Sourceforge &#8211; it&#8217;s a tool often used by programmers to see differences in text files.</p>
<p>Open a command window</p>
<p>- e.g. start &#8211;&gt; run &#8211;&gt; &#8220;cmd&#8221;</p>
<p>Create a text file with the names, sizes, and date stamps from folder &#8220;A&#8221;</p>
<p>- e.g. dir c:\the_documents\*.* &gt; this_computer.txt</p>
<p>Do the same for folder &#8220;B&#8221;</p>
<p>- e.g. dir \\that_computer\c$\the_documents\*.* &gt; that_computer.txt</p>
<p>Open both files in WinMerge.</p>
<p>- the differences in the two &#8220;dir&#8221; outputs will be higlighted for you.</p>
<p>Now if you&#8217;re still not sure if the files are the same or now, e.g. if the files are the same size but have different date stamps, then search for a utility called &#8220;md5sums&#8221;.  This will create md5 hashes of all files in a folder.</p>
<p>e.g. c:\tools\md5sums -n &#8220;\\distribution\c$\program files\cybex\*.*&#8221; &gt; distrib2.txt</p>
<p>That&#8217;s it.  It&#8217;s been a couple weeks since the last blog post. We&#8217;ve been busy at Perceptus.  Our next project is going live soon &#8211; retailers with multiple locations in BC and Alberta, watch this space.  Our next product is geared for you!</p>
