Multi Commander Crashes

Multi Commander crashes can occur due to various factors, ranging from internal software bugs to external system issues, hardware problems, or conflicts with third-party software. Understanding the crash reporting system and implementing proper troubleshooting strategies helps identify and resolve these issues effectively.

Automatic Crash Reporting

When Multi Commander crashes, it automatically creates a mini crash dump and sends it to our crash report system for analysis. This helps developers identify and fix issues quickly, but you can also take steps to provide more detailed information.

Understanding Multi Commander Crashes

Crashes occur when Multi Commander encounters an unrecoverable error that forces the application to terminate unexpectedly. Identifying the root cause is essential for effective resolution.

Internal Causes
Software-Related Issues
  • Programming bugs: Logic errors or memory management issues
  • Resource exhaustion: Memory leaks or excessive resource usage
  • Data corruption: Invalid configuration or damaged files
  • Extension conflicts: Incompatible or buggy extensions
  • File system errors: Corrupted filesystem structures
  • Threading issues: Race conditions or deadlocks
External Causes
System and Hardware Issues
  • Hardware failures: Bad RAM, failing storage devices
  • Driver conflicts: Outdated or incompatible device drivers
  • System instability: Overheating, power supply issues
  • Antivirus interference: Overly aggressive scanning
  • Third-party software: System utilities or security software
  • Windows updates: System changes affecting compatibility
Crash Analysis Process
1. Automatic Collection
  • Mini crash dump created automatically
  • Basic system information gathered
  • Crash location and stack trace captured
  • Automatic submission to crash report system
2. Analysis Processing
  • Automated crash analysis performed
  • Pattern recognition and categorization
  • Duplicate detection and grouping
  • Priority assignment based on frequency
3. Developer Investigation
  • Manual review of complex crashes
  • Root cause analysis and debugging
  • Fix development and testing
  • Release scheduling and distribution

Shell Extensions: The Primary Crash Cause

Third-party shell extensions are the most common cause of Multi Commander crashes. These extensions run within Multi Commander's process space and can cause instability when poorly coded or incompatible.

Shell Extension Risk

Shell extensions are often tested only with Windows Explorer. When Multi Commander uses these extensions for context menus and file operations, coding errors in the extensions can crash Multi Commander through no fault of the application itself.

What are Shell Extensions?
Shell Extension Types
  • Context Menu Handlers: Right-click menu additions
  • Icon Overlay Handlers: File icon modifications
  • Property Sheet Handlers: File properties extensions
  • Thumbnail Handlers: Custom preview generators
  • Preview Handlers: File preview providers
  • Column Providers: Additional file list columns
Common Sources
  • Cloud storage clients (Dropbox, OneDrive, Google Drive)
  • Version control systems (Git, SVN, TFS)
  • Compression utilities (WinRAR, 7-Zip)
  • Media software (codec packs, players)
  • Security software (antivirus, encryption)
Why Shell Extensions Crash Multi Commander
Technical Issues
  • Memory violations: Improper memory management
  • Exception handling: Unhandled exceptions propagating
  • Threading problems: Unsafe multi-threading practices
  • API misuse: Incorrect Windows API usage
  • Resource leaks: Failing to release system resources
  • Version incompatibility: Outdated or incompatible code
Impact on Multi Commander
  • Immediate application termination
  • Data loss in ongoing operations
  • System instability
  • User workflow disruption
Shell Extension Management with ShellExView
Using ShellExView by NirSoft

ShellExView is a free utility that allows you to easily disable and enable shell extensions to identify problematic ones.

  1. Download ShellExView: Get it from NirSoft's website
  2. Run as Administrator: Ensure proper permissions for system changes
  3. Identify suspects: Look for non-Microsoft extensions
  4. Disable systematically: Disable extensions one by one
  5. Test stability: Use Multi Commander after each change
  6. Isolate the problem: Identify the specific problematic extension
Systematic Testing Process
  • Backup first: Export current settings
  • Start with recent: Focus on recently installed software
  • Group testing: Disable by software vendor
  • Document results: Keep track of changes
  • Re-enable safe ones: Restore known-good extensions

Enhanced Crash Reporting

While automatic crash reporting provides basic information, configuring enhanced crash dumps provides developers with detailed information necessary for complex issue resolution.

Configuring Crash Dump Settings
Accessing Crash Settings
  1. Open Multi Commander
  2. Go to Configuration menu
  3. Select Core Settings
  4. Navigate to the Crash Dump section
  5. Choose your preferred dump format level
Multi Commander Crash Settings

Crash dump format settings in Multi Commander's Core Settings

Dump Format Levels
Available Options
  • Minimal (Default): Basic crash information, small file size
  • Standard: More detailed context, moderate size
  • Maximum: Complete memory dump, large file size
When to Use Maximum
  • Frequent crashes occurring
  • Complex or rare crash scenarios
  • Developer specifically requests it
  • Standard dumps aren't providing enough information
Crash Dump Information Levels
Level File Size Information Included
Minimal ~50KB Stack trace, basic system info
Standard ~500KB Extended context, loaded modules
Maximum 50-200MB Complete memory state, all variables
Reporting Considerations
File Size Impact
  • Storage space: Maximum dumps are very large
  • Upload time: Longer transmission to servers
  • Network usage: Significant bandwidth consumption
  • Processing time: More time for analysis
When Maximum is Worth It
  • Recurring crashes that minimal dumps can't solve
  • Complex crashes involving multiple components
  • Intermittent issues that are hard to reproduce
  • Critical workflow-blocking problems

Systematic Crash Troubleshooting

Effective crash troubleshooting requires a methodical approach to identify and eliminate potential causes while preserving diagnostic information.

Initial Assessment
Information Gathering
  1. Document the crash: What were you doing when it occurred?
  2. Note frequency: Is this a one-time or recurring issue?
  3. Check timing: Recent software installations or updates?
  4. System state: High resource usage or system load?
  5. Error messages: Any warnings before the crash?
  6. Reproducibility: Can you make it crash again?
Quick Fixes
Immediate Steps
  1. Restart Multi Commander: Clear temporary state
  2. Update to latest version: Check for recent fixes
