Luckily, this was in the days when most of the work was done on non-networked computers, so we cobbled everything together from partial source trees on floppies, hunkered down for a week to hammer out code and got back to where we were before. It&amp;#x27;s amazing how fast you can write a piece of code when you&amp;#x27;ve already written it once before.&lt;p&gt;That was the day I started backing up everything.</text><parent_chain><item><author>amenod</author><text>When disk space is limited and you are working with large files, you need to clean up after yourself.
