There are said to be two types of people - pilers and filers. I've always been a filer, but have found that as my interests spread, and my work has increasingly been to create connections, I don't know where to file things.<p>So for my paperwork I have a single "pile". Each document gets a unique reference number, it gets filed in alphanumeric order, and I keep a file with the number and every keyword I can think of that might be relevant. When I want something I do a keyword search on the file and that pops out all the related documents references, along with the other keywords so I can decide if it's actually relevant.<p>I'm doing a similar thing with texts, snippets, photos, PDFs, etc. I put everything in a wiki, migrate things freely, but retain with everything a reference number, and in an index file, a list of reference numbers with their keywords. To start with it felt like an effort, but it has paid off time and time again. Things tend to migrate to meet up with their friends, but the index means things are easy to find.<p>Search is fast, but having things migrate and cluster creates the opportunity for coincidences and serendipity to play a role.<p>Embrace, adapt, enhance, and do what works for you.<p>And have backups. Multiple backups. And test your restore process regularly.
