Abstract A method and apparatus for file storage is disclosed, wherein the method comprises: recording meta-data information of a folder, and storing the meta-data information into key-value databases; and, when the folder includes at least one sub- folder list and/or file list thereunder, storing the contents of the at least one sub-folder list and/or file list included under the folder in secondary keys based on the primary key. The method achieves "open ended" unlimited expansion of data in a directory tree storage. The use of the "open ended" unlimited data expansion scheme avoids bottlenecks related to underlying data storage when accumulated data become large. In comparison with the prior art method, the method splits and stores large data into multiple secondary keys for uniform data distribution, thereby enhances storage stability of storage databases and facilitates data expansion and systems' transaction operations. |
