Applying Changes to the Top-Level Parent File
Every file in a synchronization hierarchy has its own _Sync folder where all changes are temporarily stored. Opening the file applies these changes, making it up-to-date.
While the top-level parent file does not require the latest changes applied, opening the file applies the changes from the _Sync folder to the shared engagement file, reducing the size of the _Sync folder. A smaller _Sync folder improves performance by decreasing network bandwidth usage. Creating a sync file copies the top-level parent file, including the _Sync folder, to the local drive. Pending changes increases the size of the _Sync folder, which increases network bandwidth usage.
Open the top-level parent to resolve outstanding conflicts. As pending conflicts are stored in the _Sync folder, resolving the conflicts reduces its size.
