Advanced Features

This guide covers advanced features and functionality in FileSyncHub.

Selective Sync

Pattern-Based Sync

Configure specific patterns for synchronization:

# Include patterns
include = [
    "*.{doc,docx,pdf}",
    "Projects/**/*.rs",
    "Images/*.{jpg,png}"

    "**/.git",
    "target/"
]

Directory-Specific Rules
