Onfolio
I've been trying out Onfolio 2.0 for the past week or so and so far I really like it. I've been collecting files and webpages for afew years now on various things I'm interested in. So I've been copying files and links into Onfolio to have as a knowledge base/electronic brain. I especially like the fact that I'm not dependent on other program's file structure like how Firefox keeps the bookmarks in one folder and files in My documents with pictures, music and videos in the appropriate folders. For instance, I have a folder in My Documents labeled InuYasha, one of my favorite anime shows(how does one pluralize anime as in meaning one of many shows?). In it I have some archived fanfics I like and want to be able to read offline. In My Pictures I have two folders related to InuYasha images, one is Fanart which covers the small images from official and fanartists I like and another one is Wallpapers. In My Videos I have around 15-16 amv's (anime music videos-clips from a show or game set to music) In Firefox I have links to fanfics, fansites, the official site, links to AMV's I want to download, etc. In Onfolio I have have copies of the files and links all in one folder. I'm not dependent on desktop search to help me find all my things, although I'm going to keep using Copernic Desktop search as sometimes I'm not exactly sure where I saw something.
I'm also using Onfolio to read my feeds which is really nice. I can have nested folders and read a newspaper style view of all the feeds in a given subject area. I can also decide when to update and how long to keep things. All in all a very nicely done piece of software, one which I will definitely use for a while to come. I think it is useful in a GTD context as well, as it allows me to have electronic reference files to get reference stuff out of my head and where I can use it. I've been working on typing up my paper notes and filing them and will be adding them to Onfolio as I finish typing them. I plan on archiving the files on CD-R to save space on my HD and of course will keep Onfolio's collection file backed up in a safe place.
I got it as a promo version from O'Reilly and it was very nice. I had a problem with the capture of items though and Onfolio gave me great support and a fix for the problem in a matter of a day or so of emailing logs and detailing the problem.
