Implements

IFileSystemFilterFilterAsync(SyncDirection, OperationType, String, FileSystemItemType, String, IOperationContext)
Remarks

This method is called before calling GetFileSystemItemAsync(Byte, FileSystemItemType, IContext, ILogger) as well as each IFile, IFolder and ILock interface methods. If this method returns true, the method is NOT called.

You can use this method to exclude items from synchronization with the remote storage. For example you can exclude temporary files, hidden files, Microsoft Office lock files, backup files, etc.

The default Engine implementation returns false for all items.
