The invention relates to a method for memorizing files and restoring error deleted files, mainly solving the technical problem that the deleted files can not be restored after being deleted in the existing method. The technical scheme is that: the method for memorizing the files and restoring the error deleted files comprises the following steps of: (1) firstly, dividing a memory medium space into four states: blank, occupied, deleted and bad cluster; (2) creating a pseudocycle queue in the memory medium partition; (3) creating a pointer region in the memory medium partition; (4) when needingto memorize the files, directly distributing the memory medium space corresponding to a starting position of the blank region to the files; (5) when deleting the files, placing an index of the space occupied by the files to a final position of the deleted region of the pseudocycle queue by exchanging data of a corresponding unit in a cycle queue region; and (6) when needing to restore the deletedfiles, finding the files in the deleted region and restoring the files.
