After comparing two folders, you can use the screen menu or the action menu button at the top right hand side of the compare tab to start a sync operation. As of version 2.4.0, Syncs started from within the outline view context menus also allow you to sync just specific folders and their descendants.

Several types of Sync are available

• Mirror Left to Right (Left is source, right is target)
• Mirror Right to Left (Right is source, left is target)
• Update Left to Right (Left is source, right is target)
• Update Right to Left (Right is source, left is target)
• Sync Both Ways

Mirror means copy newer files from source to target, copy orphans from source to target, delete orphans on target.

Update means copy newer files from source to target, copy orphans from source to target, leave orphans on target as-is.

As of version 2.4.0, all Sync Types available within the app can be customised by the user within the app preferences.

Folder Sync never commits any changes to disk without first showing you a Sync Preview. If you dont like what you see in the preview, simply Cancel. Note that it is also possible to select individual actions within the Sync Preview to remove them from the Sync.
