A treewalk for splitting a file directory is disclosed for parallel execution of work items over a filesystem. The given work item is assigned to a worker. Thereafter, a request is sent to split the file directory to share a portion of the file directory with another worker. The worker examines the file directory for a next splittable directory entry key after a current in-progress location within a key space for the file directory. If no key is detected, the file directory is identified as unsplittable. If an entry is detected, the key space is progressively searched for a next entry between a next available directory entry key and an upper boundary. The worker identifies the file directory as splittable if the next available entry is found, providing a range of entries within the file directory for which parallel execution of the work item.
