To synchronize folders (directories) means to create or delete folders in synchronization-partner locations to match the user's actions in one of those locations. The same algorithm is used to synchronize folders (directories) as is used to synchronize files. Files within a folder are synchronized independently of the folder itself.
Folder attributes are copied when Allway Sync creates a folder on another device. However, unlike most folder backup programs, this synch software doesn't copy attributes if both the source and target folders already exist.
