searching a configuration value corresponding to the operation mark information from the preset mark configuration definition table;
according to the FAT/exFAT file management standard, traversing directory entries corresponding to all files, and selecting files containing the mark fields in the corresponding directory entries from all the files;
and judging whether a file with the configuration value of the mark field consistent with the configuration value corresponding to the operation mark information exists in all the files containing the mark field.
7. The file marking method of claim 1, wherein before performing the configuration clear operation on the unused field, further comprising:
obtaining the value of the unused field, and storing the value of the unused field in a preset mark file modification record table;
and when an original configuration instruction for recovering the marker file is received, modifying a record table by using the preset marker file, and recovering the value of the unused field.
8. A document marking apparatus, the apparatus comprising:
the file configuration zero clearing module is used for creating a file, acquiring an unused field of the file from a directory entry corresponding to the file, and executing configuration zero clearing operation on the unused field;
the file marking generation module is used for analyzing and obtaining marking information from a marking instruction when the marking instruction of a user on the file is received; configuring the unused field after configuration and clearing by using the marking information and a preset marking configuration definition table, and setting the unused field as a marking field of the file;
the file marking matching module is used for analyzing and obtaining operation marking information and operation information from the instruction of the file operated according to the mark when the instruction of the file operated according to the mark by the user is received; judging whether all files have files with the tag information configured by the tag field consistent with the operation tag information;
the file marking application module is used for sending the prompt information for setting the mark if the file with consistent marking information does not exist; and if the files with consistent marking information exist, taking the files with consistent marking information as object files, and executing corresponding operation on the object files according to the operation information.
9. An electronic device, characterized in that the electronic device comprises:
at least one processor; and the number of the first and second groups,
a memory communicatively coupled to the at least one processor; wherein the content of the first and second substances,
the memory stores instructions executable by the at least one processor to enable the at least one processor to perform a file marking method as claimed in any one of claims 1 to 7.
10. A computer-readable storage medium, in which a computer program is stored which, when being executed by a processor, carries out a file marking method as claimed in any one of claims 1 to 7.
