• (A) reading data of a sector from the storage device;
• (B) filtering a directory entry from the data of the sector;
• (C) concatenating the filename from the data read when the directory entry filtered is not free, and executing step (B) when the directory entry filtered is free and followed by another directory entry;
• and
• (D) setting the directory entry to be free when the filename concatenated is a target file to be deleted, and conversely executing (A).
