Document Management


It is estimated that 80% of all business information is stored solely on paper. This part of the modern office has never changed. Paper documents are still filed away in traditional filing cabinets. Retrieving these documents can be an aggravating experience. Often documents are lost or misplaced. There is rarely a backup of this data. A disaster could easily destroy 80% of a business's proprietary data.

This is what document management is designed to improve. Document management is the process of digitizing your paper documents into a searchable online library of information.

The document management process integrates a number of technologies to create, store and manage your digital documents library. Computers are used to store and retrieve the documents and scanners are used to digitize your paper into electronic format. Computer networks allow access to your digital documents from remote locations, whether these locations are across the office, or across the world.

Once your data has been digitized, you can easily create backup copies to store off-site. This ensures that your business will survive any disaster.

The document management process also offers massive productivity improvements for your staff. Documents don't become lost since there is no need to re-file. Also, since the documents are now electronic, they can be viewed by many people at once. No more hunting for files in the office.

Staff that work from remote locations can gain instant access to the documentation that they require. Just bring up the documents securely over the Internet, or your corporate virtual private network (VPN).

Unique Product

New generation of business software

Sentry File is pioneering a new generation of business software that offers unparalleled value by:

  1. Minimizing the complexity of the software to ensure that staff require only minimal training.

  2. Using only standards-based technologies to ensure that your data is always accessible no matter how future technologies change.

  3. Reducing the client workstation requirements to ensure that you extend the lifespan of your current technology investment.

  4. Simplified "server-based" licensing ensures that as your organizations grows you won't incur additional software costs.

These concepts will ensure that Sentry File offers the lowest total cost of ownership of any software package your organization uses.

Minimized complexity

Sentry File is designed to be "as easy as possible". This concept means each user, based on their rights profile, is only displayed interface items for features that they require. This keeps the interface clean from any items that are not required and can be customized on a user or group level.

Standards-based technologies

Sentry File is a completely non-proprietary system. This means that the application conforms to industry standards. This is crucial for businesses in the new economy. Information must be accessible no matter how future technologies change. With Sentry File, rest assured that your data is always YOUR data.

Reduced workstation requirements

Sentry File requires no additional software to be installed on your staff workstations. We use the existing software that you already have such as your Web Browser and your PDF Viewer. This lessens the stress on your existing technology and extends its lifespan.

Server-based licensing

Typically, software is licensed on a per-user or client basis. This means that each person that uses the software requires a separate license. Sentry File however is sold on a per-server basis. You can install Sentry File on one computer in your organization and allow virtually unlimited number of users to connect from their workstations. No additional licenses are required.



Sentry File Enterprise Edition features advanced Workflow capabilities that allow you to route documents throughout your organization while maintaining the ability to track their progress and subscribe to email notifications on their status. Each workflow consists of two components:

  1. One or more "triggers" to cause a document to be entered into a workflow

  2. One or more "steps" that the document is routed through to be processed

Triggers are actions that occur within the system, such as adding a document to a cabinet, modifying a document, adding pages, etc. These triggers can be further refined by specifying specific users that will cause the trigger to activate, and by specifying index field criteria to filter on documents meeting specific requirements.

Steps are the people who will perform one or more tasks on a document. Each step can include a series of instructions for the user that outlines the set of tasks they must complete. Once completed the user can either "Approve" or "Reject" the document. Approval moves the document to the next step in the workflow. Rejection sends the document back to a previous step in the workflow, or removes the document completely from the workflow. The rejection action is configured by the administrator when creating the workflow.

Highly customizable email notifications and system alerts allow your users to set their own preferences on how they are notified about documents being processed through the workflow. These settings can be assigned globally to all workflows, while still providing users the ability to set exceptions on specific workflows.

Technical Explaination

Software platform

Sentry File is a web-based document system written as a set of .Net Active Server Pages ( The software runs on Microsoft Internet Information Server (IIS). IIS is included with Windows. The Microsoft Index Server provides full-text searching capabilities. This software is also included with Windows.

Client computers access the system using Microsoft Internet Explorer. If your client PC's already have Internet Explorer installed, there is no requirement to install additional client software. Simply provide your staff with a URL that points to your Sentry File server. All client workstations can scan documents to the system directly through Internet Explorer with an ActiveX control. This control provides imaging and Twain capabilities that would normally not be available in a web application.

Users, Groups and Integration

Sentry File can authenticate users in numerous ways. The system allows for authentication against a Sentry File internal user list, Windows Active Directory, POP/IMAP mail servers, FTP Servers, or another Sentry File Server. The flexibility of our authentication module gives you the ability to ensure that "lost passwords" are a thing of the past.

Document Types / Data Storage

Documents that are uploaded to the system are stored in their native format as flat files within the file system. They are not encapsulated within a database. All index data entered is stored in a Microsoft SQL Server Database. If you don't own Microsoft SQL Server we include a copy of the Free SQL Server Express Edition. All data within the database is left in its natural state (no encoding of the data values).


Tiff documents that are uploaded to the system are auto-converted to PDF format. Scanned document can also be recognized by our integrated Optical Character Recognition (OCR) engine. This will allow you to full-text search for documents that have been scanned and OCR'd.

Full-Text Search

Microsoft Index Server provides full-text search. Index Server works in the background with little or no administrative interaction required. Essentially, Index Server "watches" all documents within Sentry File. When new documents arrive they are indexed for full-text searching. Natively supported formats are all Microsoft Office Formats such as Word (DOC/DOCX), Excel (XLS/XLSX), and PowerPoint (PPT/PPTX) etc. Other file types can be supported by installing appropriate IFilters. IFilters are typically provided by third parties free of charge. For instance, Adobe provides a free IFilter for indexing PDF documents with Index Server (We include the PDF iFilter with Sentry File). IFilters are available for a wide range of other products including Corel WordPerfect, XML, MP3 and more.


Sentry File can integrate within almost any backup system. Sentry File resides within a folder typically called "c:\inetpub\wwwroot\sentryfile" or similar. To backup the system simply includes the installation folder within your backup regimen. Many current customers use technologies such as Tape backups, DVD backups, Network Attached Storage (NAS) and removable hard disk technologies to achieve their backup requirements.

Internet Connectivity

Your Sentry File installation can be made available on the Internet if you choose. Many of our clients prefer to have their installation only available on their private LAN. Making your Sentry File installation available over the Internet requires a full-time dedicated Internet Connection. After this, it is necessary to ensure that the IP address is available through any firewalls or gateways installed within your organization. Sentry File supports secure 128-bit encrypted connections, commonly used in e-commerce and online banking applications. In order to achieve this it is necessary to install a digital certificate within IIS, they can be purchased through companies such as Verisign, or you can generate one yourself.

System Requirements

Sentry File is an (Active Server Pages) application. It runs on a Microsoft Windows platform and uses the Microsoft Internet Information Server (IIS) and Microsoft Index Server. Both IIS and Index Server is included with Windows Server.

Server Requirements

  • Microsoft Windows Server 2012 64bit or newer

  • Microsoft Windows SQL Server 2017 or newer

    • Microsoft SQL Server Express is ​usable

  • Minimum 16GB RAM

  • Minimum 7GB free drive space for Sentry File Software 

(NOTE: Windows Home, Pro, or other operating systems primarily designed as client workstation operating systems strongly discouraged as a server platform, and definitely NOT recommended for a production "real world" environment.)

Client Requirements

Microsoft Windows 10 or later

Google Chrome browser (other browsers supported with limited functionality)


We recommend Google Chrome for use with Sentry File. Other browsers, such as Firefox, Opera, Internet Explorer, and Safari will have limited functionality within the system. 

Calculating Storage Space Required

To determine the hard disk storage space required for your implementation of Sentry File, we recommend the following formula:


  • Size of typical 8.5X11 page scanned at 300dpi: approximately 50 Kilobytes

  • Typical number of pages in a 4-drawer letter size filing cabinet: approximately 12,000


Next, count the number of 4-drawer (or equivalent) filing cabinets in your operation. Then, use the formula below to determine the amount of hard drive space required:


50Kb   X   12,000   X   #Cabinet



=  Storage required in Gigabytes.

Please ensure that you also include appropriate room for growth over the expected lifetime of the hard drive storage to accommodate future demand.
