Abstract

Disclosed is a method implemented by a computer system that comprises a file system. The file system comprises first, second, third, and fourth directories wherein the first and second directories are sub-directories of the third directory, the third directory is a sub-directory of the fourth directory, the first directory stores only files identified by a first file extension, the second directory stores only files identified by a second file extension, and the first and second file extensions are distinct. In one embodiment, the method comprises receiving first and second requests to open first and second files, respectively, that are contained in the file system. The first and second requests comprise first and second file system paths, respectively. The first file system path comprises a first file name, and the first file name comprises the first file extension. The second file system path comprises a second file name, and the second file name comprises the second file extension. The first file system path is modified by adding identities of the first, third, and fourth directories to the first file system path. The second file system path is modified by adding identities of the second, third, and fourth directories to the second file system path.
