Office AutoSave Backup
WindowsFreeA free utility that automatically backs up your Microsoft Office autosave files with intelligent version management and easy recovery.
Overview
We built this after watching attorneys lose hours of work to crashed documents and disappeared autosaves. Office's built-in recovery is helpful when it works, but those files can vanish—after a crash, an update, or just closing the wrong dialog at the wrong time.
This utility runs quietly in the background, watching Office's autosave folders and keeping timestamped copies organized by document. When something goes wrong, you open it up, find your file, and restore—no digging through folders of cryptically-named temporary files.
Everything stays on your machine—no cloud, no account, no data leaving your computer. It's free for anyone to use. If it saves you from recreating a brief or a contract even once, it's done its job.
Features
Automatic Monitoring
Continuously monitors Office autosave locations and backs up files at configurable intervals (1-60 minutes). Runs silently in the background without disrupting your work.
Multi-Application Support
Supports Microsoft Word and Excel with easy extensibility for PowerPoint. Automatically detects and monitors all configured Office applications.
Intelligent File Handling
Handles file locking gracefully when Office has documents open. Uses retry logic and async I/O to ensure reliable backups without blocking your work.
Organized Backup Management
Master-detail interface groups backups by document with version history. Easy browsing, searching, and one-click restore functionality.
Automatic Cleanup
Configurable maximum backup versions per file. Automatically removes old backups to conserve disk space while maintaining your recent work history.
System Tray Operation
Runs in the system tray with optional startup on Windows boot. Start minimized option keeps your workspace clean while protection runs in the background.
Interface
The application features a modern, two-panel interface inspired by Windows 11 design language. Documents are grouped on the left with version counts, while individual backup versions display on the right with timestamps and file details.
Master-Detail View
Documents grouped on the left, versions displayed on the right for clear navigation
Real-Time Search
Filter documents instantly as you type to find backups quickly
Visual Indicators
Color-coded status, version badges, and file type icons for clarity
Use Cases
Accidental Document Loss
Automatic backups ensure you can recover work even if you close without saving or experience an unexpected shutdown.
Version History Tracking
Multiple timestamped versions let you roll back to earlier states of your documents throughout your work session.
System Crash Recovery
Backups are stored separately from Office autosave locations, providing an additional layer of protection against system failures.
Multi-Document Workflows
Master-detail view makes it easy to manage backups across dozens or hundreds of documents without overwhelming interfaces.

Architecture Notes
The application follows Microsoft best practices for WPF development, using the MVVM pattern to separate UI concerns from business logic. Services are injected via dependency injection, making the codebase testable and maintainable.
File operations use FileShare.ReadWrite to handle Office documents that may be locked during active editing sessions. Retry logic with configurable delays ensures reliable backups even when files are temporarily inaccessible.
