 - No limitations: An arbitrary number of      files can be synchronized. 
 - Unicode support. 
 - Network support. 
 - Built-in support for very long filenames      (more than MAX_PATH = 260 characters). 
 - Synchronization database for propagation      of deleted files and conflict detection 
 - Support for multiple folder pairs with      distinct configuration 
 - Full support for Windows/Linux Symbolic      Links and Windows Junction Points. 
 - Lean & easily accessible UI: Highly      optimized for speed and huge sets of data. 
 - Algorithms coded in C++ completely. 
 - All progress indicators optimized for      maximum performance! 
 - Create Batch Jobs for automated      synchronization with or without GUI. 
 - Focus on usability: 
 - Only necessary functionality on UI: no       overloaded menus or icon jungle. 
 - Select all folders via drag & drop.       
 - Last used configuration and screen       settings are saved automatically. 
 - Maintain and load different       configurations by drag & drop, load-button or commandline.

 - Ignore directories "\RECYCLER"      and "\System Volume Information" with default Filter. (Windows      only) 
 - Localized versions are available for      many languages. 
 - Delete before copy: Avoid disc space      shortages for large sync-jobs. 
 - Filter functionality to include/exclude      files from synchronization (without requiring a re-compare!). 
 - Include/exclude specific files from      synchronization temporarily.

 - Create regular backups with macros      %time%, %date% within directory names 
 - Copy file and folder      create/access/modification times when synchronizing 
 - Advanced locking strategy to allow multiple synchronization processes (e.g. multiple writers, same network share)
