  • File Size Limitations: Some devices have file size restrictions
  • Operation Overhead: Protocol overhead affects small file transfers
  • Device Dependencies: Performance varies by device implementation
Operational Differences
  • No Drive Letter: Accessed through Windows Portable Device API
  • Limited Operations: Some filesystem operations may not be available
  • Device-Specific Features: Capabilities vary between device manufacturers
  • Connection Dependencies: Requires device to be awake and responsive
