13 AT Commands for File System

The file system is used to store files in a hierarchical (tree) structure, and there are some definitions and
conventions to use the Module.
Local storage space is mapped to "C:", "D:" for TF card, "E:" for multimedia.
NOTE: General rules for naming (both directories and files):
1 The length of actual fully qualified names of directories and files can not exceed 254.
2 Directory and file names can not include the following characters:
\ : * ? " < > | , ;
3 Between directory name and file/directory name, use character "/" as list separator, so it can not
appear in directory name or file name.
4 The first character of names must be a letter or a numeral or underline, and the last character can
not be period "." and oblique "/".
