Tagsistant is a semantic filesystem. So, the question becomes: what is a semantic file system? It's a new way to organize files on disk, using tags in place of directories. Let's see the difference. In a traditional filesystem, files are organized using directories. As you know, a directory is basically a container for files and other directories, which are usually called subdirectories. Basically, a file can be found in one or more directories, using features like links. This seems to be quite a rational approach to file storage, and from a computer perspective it is indeed. But from the human point of view? The main drawback of traditional filesystems surfaces later, when you need to access your files. You must remember where you placed what. Otherwise you have to search through the filesysem. And what is worse, you can't ask the computer to do the search for you. In fact, you can't look for something that is located here and there, like in the music directory and in the concert directory and in the London directory at the same time. It's all up to you. But what is really painful is looking for a file, let say a photo of an old friend, which your camera called PIC_83672.jpg and you left in a directory called, well, "stuff". You'll never find it. That's where Tagsistant enters. |
