Tags4Docs introduces the handy Web 2.0 tag cloud functionality on your PC. You could see that later and though, why this isn't implemented for my local documents as well and here it is! With Tags4Docs you simply assign different tags to any document, which would describe its contents best of all. Then, whenever you need this document you make an instant search clicking through tags and it comes to your eyes one second later. You don't have to remember the name of the file, or the path where that document is stored. All you need to know is tags, and since tags are written in a natural language basing on the content of a document - you never forget them!
You can assign many tags to a single document to make it easier to find. Let's say you don't remember the name of a file, but you know for sure it was a text about recent changes in the tax regulation. So you click the tags text, 2010, taxes and here it is - the document you need. Another trick is to assign a tag to some folder which is a huge time saver when you have a lot of similar documents in the same folder.
