When synchronizing two folders, only the files that are present in both those folders are synchronized — all other files are left unchanged.
Delete Obsolete Items
Any file in the destination folder, that is not present in the source folder, is deleted upon completion of the synchronization. This option is rendered useless when the Also Synchronize in Reverse option is enabled. This is because SwitchBack would not know whether to copy a file to the source (or destination) folder, or remove a file from the destination (or source) folder.
Resolve Aliases
With this function enabled the target that the alias refers to will be copied instead of the alias file itself. If the target of the alias resides on an unmounted volume, that volume will automatically be mounted. This may require you to insert a floppy disk, or enter a username and password for a shared volume. This option enables quick and efficient synchronizing of files over a network. When performing a one-way synchronization it does not really matter what the name of the alias is. However, with a two-way synchronization, or when deleting obsolete items, it is very important that the alias name matches the name of its target. This is because SwitchBack relies on names to compare files and folders. It would have no way of knowing, for example, that a source filename of “My Doc” should be compared with a destination filename of “My Doc Alias”.
Alias resolving can be: off, to one level or complete.
Off — when checked, alias files are copied as is. The file or folder to which they refer is ignored.
To One Level — when checked, only those aliases in the source (or destination) folder itself will be resolved. This allows you to set up a folder of aliases to synchronize with, while not resolving aliases in dependent folders.
Completely — when checked, all aliases will be resolved.
Version Control
This item applies to developers. Any files that are checked out as read-only will treated as if they are locked, and not overwritten.
Copy Folder Attributes
The Finder information about each folder is not normally retained. With this item checked, the folder size, window position etc. will remain the same in both the source and destination folders.
