DocShield is a software program for Microsoft Windows operating systems that is designed to prevent or remedy the catastrophic loss or accidental modification of important electronic documents. It protects these documents by continually monitoring them for changes, then creating and storing snapshots of those documents as they change through time. DocShield's operation is "passive" because it will never delete nor modify your documents.
