One-way syncs allow you to specify file modifiers that can change how a file is copied to the destination. Each file modifier is applied to all copied files by default, but can be adjusted individually to match a subset of the copied files.
Adding a Finder tag allows to recognize all files copied during a sync, assuming that the tag wasn’t set before.
Compressing big or rarely needed files allows to save space, but requires expanding them before using them again.
Creating an alias pointing back to the source file allows to save space of rarely needed files, but renders the alias useless if the source file is deleted or disconnected.
Renaming files allows to change or delete characters that are not supported on the destination volume.
You can choose to find and replace text in a file name by selecting one of two operations: Exact match or Regular expression.
