Method of displaying directory structure of recorded data

A computerized system to display the structure of a directory of file data stored in a recording medium that contains a plurality of directories, wherein any directory is capable of containing files having different attributes, comprising:

• means for pre-specifying a file attribute;
• computerized means for examining the structure of the file data, including file attributes, to determine whether or not a directory that is capable of containing files having different attributes includes at least one file having a the pre-specified attribute on the recording medium;
• computerized means for generating a mark for indicating the result of the examining step;
• and
• computerized means for displaying the generated mark on the directory as an indication that the directory that is capable of containing files having different attributes includes at least one file having the pre-specified attribute.

A computerized method of displaying directories of files contained on a recording medium that contains a plurality of directories, wherein any directory is capable of containing flies having different attributes including at least one ‘MP3’ file, and the number of files having attributes other than an “MP3” attribute, and excluding any file that does not have an “MP3” attribute from the displayed directory without requiring a user of a device or system using the memory to open and check all directories individually to obtain file attribute information, comprising:

• a1) pre-specifying at least one file attribute
• a2) computerized reading of recorded file system data;
• b) computerized recognizing of the directory structure and respective attributes of files on the recording medium;
• c) computerized flagging of every directory on the recording medium that contains a plurality of directories, wherein any directory is capable of containing files having different attributes including the at least one pre-specified file attribute;
• d) computerized composing of directory-display information that differentiates flag-set directories from other directories by adding a specific mark to the flag-set directory display;
• and
• e) computerized displaying of composed directory-display information.

• f) computerized means for reading recorded file system data;
• g) computerized means for recognizing the directory structure and respective attributes of files on the recording medium;
• h) means for pre-specifying at least one specific file attribute and computerized means for flagging every directory on the recording medium that contains a plurality of directories, wherein any directory is capable of containing tiles having different attributes including said at least one pro-specified file attribute;
• i) computerized means for composing directory-display information that differentiates flag-set directories from other directories by adding a specific mark to the flag-set directory display;
• and
• j) computerized means for displaying composed directory-display information.

A computerized method for displaying directories of files contained on a recording medium that contains a plurality of directories, wherein any directory is capable of containing files having different attributes including at least one specific file, and the number of files having attributes other than an attribute of the at least one specific file, and identifying any directory having a file that does not have the attribute of the at least one specific file from the displayed directories without having to open and check all the directories individually to obtain file attribute information, the computerized method comprising:

• pre-specifying at least one file attribute;
• computerized reading of recorded file system data;
• computerized recognizing of a directory structure and respective attributes of files on the recording medium;
• computerized flag-setting of at least one directory on the recording medium that contains a plurality of directories, wherein the at least one directory is capable of containing files having different attributes including the at least one pre-specified file attribute, and wherein the at least one flag-set directory contains at least one file having attributes including the at least one pre-specified file attribute;
• computerized composing of directory-display information that differentiates the at least one flag-set directory from other directories by visually differentiating the at least one flag-set directory from the other directories;
• and
• computerized displaying of the composed directory-display information.
