# Scanning Settings

Control how Power Scraper Pro finds and identifies media files.

## File Types

### Supported Video Extensions

Select which file types to scan for:

* **MKV** ✓ (recommended container)
* **MP4** ✓
* **AVI** ✓
* **M4V** ✓
* **MOV** ✓

Uncheck any formats you don't use to speed up scanning.

## File Filters

### Minimum File Size

Ignore files smaller than this threshold:

* **Default**: 100 MB
* **Purpose**: Filters out trailers, samples, and small clips
* **Range**: 0 MB - 1000 MB

<Tip>
  Set to 0 to include all files, or increase to 500 MB if you have many large trailers being detected.
</Tip>

### Delete Sample Files

Automatically delete detected sample files:

* **Off** (default): Sample files are ignored but not deleted
* **On**: Files matching sample patterns are deleted

<Warning>
  Only enable this if you're sure you want sample files permanently removed.
</Warning>

### Sample File Patterns

Files matching these patterns are considered samples:

* Contains "sample" in filename
* Contains "trailer" in filename (optional)
* Files in "Sample" folders

## Folder Handling

### Recursive Scanning

* **On** (default): Scan subfolders
* **Off**: Only scan the selected folder, not subfolders

### Ignore Hidden Files

* **On** (default): Skip files/folders starting with `.`
* **Off**: Include hidden files

### Ignore Folders Named

Skip folders matching specific names:

* Default: `@eaDir`, `.@__thumb`, `#recycle`
* Add custom folder names to ignore

## NAS Optimization

### Enable NAS Mode

Optimizations for network-attached storage:

* Single-pass scanning (reduces network requests)
* Larger read buffers
* Automatic disconnection handling

<Info>
  NAS mode is auto-detected for SMB/AFP/NFS volumes but can be forced on for any folder.
