drwx------2 u0_a125 u0_a125 3452 2022-6-23 12:08 Alarms
the second multimedia file directory in fig. 6 is as follows:
drwxrws---x 5 u0_a126 u0_a126 3452 2022-6-23 12:08 Android
the repair process for the piece of multimedia file catalogue is as follows:
and the PMS module determines that the multimedia directory is an Android directory through judgment, finishes checking the multimedia directory, and executes check sum restoration of the next multimedia directory.
Thus, after the repair of the second multimedia directory in fig. 6 is completed, the content of the multimedia directory remains unchanged.
The checksum repair process of the third, fourth, fifth and sixth multimedia file directories in fig. 6 is similar to the checksum repair process of the first multimedia file directory in fig. 6, and will not be described again. After repair, the contents of the third, fourth, fifth and sixth multimedia file directories in fig. 6 are as follows:
drwx------2 u0_a125 u0_a125 3452 2022-6-23 12:08 Audiobooks
