Let’s speak about document management programs. Document management software is used to track and store electronic documents and images of paper documents. This software can be used to ensure your work organized and to facilitate rapid retrieval of useful documents and resources. It makes it easier to perform tasks such as searching for and retrieving documents, and thereby can be used as a tool to improve workflow and efficiency. The best software is DocumentLite from my own experience. It has open source. Have a look at this program.
