InfoValet for Mac

From IntelliSoft:

Today's personal computers come with Operating Systems (OS) whose file system is based on a single file name and a single location to store your files. The need for better tools with more sophisticated features, in order to manage the exponentially growing flood of information that comes to us daily, is very much needed. The two biggest constraints in our current Personal Computer Operating Systems today are: - Files can have only one name - Files should only be stored in one location. InfoValet overcomes the limitation of "One name per file"by allowing you to assign 'Metadata' to a document, whenever you import a document into the InfoValet database. Metadata can be thought of as specific keywords of your own choice that you assign to a document. This metadata consists of a subject line and a nearly unlimited number of key phrases, which help you later in finding and grouping your documents. Once a document is in the database, you can easily modify the initial metadata. InfoValet comes with a search engine that uses this metadata to locate a specific document that may be hidden somewhere in your hard drive(s). To eliminate the 'One location per file' limitation, InfoValet allows you to set up a 'Virtual Folder Structure'. A virtual folder can be thought of as an imaginary filing cabinet that holds references to the original document. We specifically say reference and not copy because no documents are duplicated. Once imported in the InfoValet database, you can store any document in as many virtual folders as you like, without duplicating any information. Storing or moving documents around in the virtual folders structure is done by a simple drag and drop.
