A method for inserting a file in a search tree (B-tree) implemented on a file system, includes: (a) in response to a current node being a root node or an internal node, determining a child node; (b) repeating (a) until a leaf node is detected; (c) in response to a number of leaf nodes at a level of the leaf node exceeding an upper limit of files or a number of child nodes of a current node exceeding an upper limit of sub-directories, balancing the level of the leaf node or child nodes; and (d) inserting the file at the level of the leaf node. |
