Method of accessing files in electronic devices

摘要

In a method for accessing files in an electronic device, a Random Access Memory (RAM) disk is set-up to store the file system root of the electronic device. At least one file system to be mounted is discovered in the electronic device. Mount points are established on the RAM disk for each file system. Drive identifiers are assigned for each file system. A file access request comprising a first file name path comprising a drive identifier is detected. The drive identifier is mapped to a mount point and a second file name path based on the mount point and the first file name path is formed. Thereupon, a file is accessed using the second file name path in the electronic device.

1. A method, comprising:
discovering at least one file system to be mounted in an electronic device; establishing mount points on a Random Access Memory (RAM) disk for each said file system; assigning drive identifiers for each said file system; detecting a file access request for a specified file comprising a first file name path and a drive identifier; parsing the first file name path and determining whether the drive identifier is present; extracting the drive identifier; mapping said drive identifier to a mount point and to a list of logical drive identifiers; forming a second file name path based on said mount point and said first file name path; accessing the specified file using said second file name path in said electronic device; determining the specified file is stored in one of the logical drive identifiers; replacing the drive identifier with the logical drive identifier that stored the specified file responsive to the specified file being identified in one of the logical drive identifiers; checking at least one logical drive for presence of at least a first predefined directory; forming at least one file search path comprising an entry for each logical drive on which said first predefined directory was present; and storing said at least one file search path to at least one environment variable comprising at least one of program directories on each logical drive and library directories on each logical drive.
