Sync Method

Sync method defines "how to synchronize". It lets you control the sync process.

Update all changes in source to target folder and vice versa. For example: You add a file in source folder, it will be added to target folder too; You delete a file from target folder, it will be deleted from source folder too. etc.

Similar to above sync method. The difference is: Instead of deleting obsolete file, it will copy obsolete file to another side.

Copy all changed files in source folder to target folder. But didn't touch the files if they are changed in target folder only.

Update target file and delete the files which didn't exist in source folder no longer

This sync method is like a 'mirror' functionality. The target folder will be an exact copy of source folder. This means that all modifications in the target folder will be discard.
