🎯 Detection Logic Comparison

DeleteSamples.py Detection

# Basic string matching only
for ident in SampleIDs:
    if ident.lower() in filePath.lower() and not ident.lower() in inputName.lower(): 
        return True

Limitations:

  • Simple substring matching
  • Can miss variations like sample_preview.mkv
  • No word boundary detection
  • Limited pattern flexibility

RemoveSamples Detection

# Advanced pattern matching with word boundaries
sample_patterns = [
    r'\bsample\b',           # Word boundary matching
    r'\.sample\.',           # Dot-separated patterns
    r'_sample\.',            # Underscore patterns  
    r'-sample\.',            # Dash patterns
    r'^sample\.',            # File starting with sample
    # ... plus more sophisticated patterns
]

Advantages:

  • Word boundary detection prevents false positives
  • Multiple pattern types for comprehensive coverage
  • Configurable pattern sets
  • Directory name pattern matching

🔧 Configuration Comparison

DeleteSamples.py Configuration

# Hard-coded in script header - requires file editing
#mediaExtensions=.mkv,.avi,.divx,.xvid,.mov,.wmv,.mp4,.mpg,.mpeg,.vob,.iso
#maxSampleSize=200
#SampleIDs=sample,-s

Problems:

  • Manual file editing required
  • No validation of settings
  • Easy to break with syntax errors
  • No user-friendly interface
  • Single size threshold for all media

RemoveSamples Configuration

{
  "Remove Directories": {
    "type": "select",
    "options": ["Yes", "No"],
    "default": "Yes"
  },
  "Video Size Threshold": {
    "type": "number", 
    "default": 150,
    "description": "Size limit (MB) for video samples"
  }
}

Advantages:

  • Modern dropdown interface
  • Input validation
  • Separate thresholds for video/audio
  • Descriptive help text
  • No file editing required

📁 Directory Handling

DeleteSamples.py

# Only processes individual files
for file in filenames:
    # ... file processing only

Limitation: Cannot remove sample directories like samples/, SAMPLE/, etc.

RemoveSamples

# Handles both files AND directories
def should_remove_directory(self, dir_path, dir_name):
    # Advanced directory pattern matching
    for pattern in self.directory_patterns:
        if re.search(pattern, dir_name, re.IGNORECASE):
            return True
    return False

Advantage: Removes entire sample directories and their contents.

🎵 Audio File Support

DeleteSamples.py

  • Audio Extensions: Hard-coded, no audio-specific handling
  • Size Threshold: Same 200MB limit as video (inappropriate for audio)
  • Detection: Video-focused patterns only

RemoveSamples

  • Audio Extensions: Configurable list (.mp3, .flac, .aac, etc.)
  • Size Threshold: Separate 2MB default (appropriate for audio samples)
  • Detection: Audio-aware pattern matching

🔍 Sample Detection Examples

Scenario: File named Movie.2023.sample.preview.mkv (50MB)

DeleteSamples.py Result:

✅ DETECTED (contains "sample")
Logic: Basic substring match found "sample" in filename

RemoveSamples Result:

✅ DETECTED (pattern match + size)
Logic: Word boundary pattern '\bsample\b' matched + under 150MB threshold
Reason: Advanced pattern recognition with size validation

Scenario: Directory named SAMPLES/ with multiple files

DeleteSamples.py Result:

❌ NOT DETECTED
Reason: Cannot process directories, only individual files
Result: Sample directory remains with all contents

RemoveSamples Result:

✅ DETECTED AND REMOVED
Logic: Directory pattern matching detected "SAMPLES"
Result: Entire directory and contents removed

Scenario: File named soundtrack.sample.mp3 (5MB)

DeleteSamples.py Result:

❌ NOT DETECTED  
Reason: 5MB > 200MB threshold (inappropriate for audio)
Result: Large audio sample files missed

RemoveSamples Result:

✅ DETECTED
Logic: Audio file > 2MB audio threshold + sample pattern
Reason: Separate audio/video thresholds + audio file detection

User Testimonials

"Switched from DeleteSamples.py to RemoveSamples and immediately started catching sample directories that the old script missed. The GUI configuration is so much better than editing files."

— NZBGet User

"Finally, proper audio sample detection! The old script would miss small audio samples because of the 200MB limit. RemoveSamples caught them all."

— Media Server Admin
