When you first run Docsvault, you're confronted with categories of various types, such as Accounts Payable, Accounts Receivable, and so on, but they're empty. There's no explanation of how to put documents into them, or how to handle them once they're there. Click around some, and you'll find that if you right-click a folder, you can import documents into it, or scan documents into it.
Once you have documents in the program, you can view them, search through them, track them, and so on. But doing all that is not particularly intuitive. Different people, of course, handle documents in many different ways, and have their own personal workflow. So it may be that Docsvault is right up your alley. But be prepared to spend time getting to know it before you can use it.
Note that if you run Docsvault Professional in Windows Vista, you'll have to run it as an administrator. Right-click the program, and choose Run as Administrator to do it. Also, note that the trial version of this program only allows you to scan in up to 100 documents.
