File management method and device

The invention provides a file management method and a file management device. The file management method comprises the following steps: acquiring operating information of a file, wherein the operating information contains operating information of a first file node and/or attribute operating information of a second file node, and establishing a multi-way tree according to all the file nodes and corresponding attribute information; operating a first text node through an API interface invoked by a PYHTON script program according to the operating information; and operating the attribute of a second text node through the multi-way tree according to the attribute operating information. A DEF file is compiled by means of the API interface invoked by the PYHTON script program and an operation of the multi-way tree, so that operations are accomplished locally without being uploaded to a server end, and therefore, the consumption of resources is reduced; and moreover, the DEF file is verified after operation each time,
