6-1-2 File Operation Restrictions
This section explains which operations are possible on files stored in each directory.
When required, the following operation tables distinguish reading and overwriting from partial reading and overwriting.
Read: Read data sequentially from the start to the end of the file.
Partial read: Read only a part of the data in the file.
Overwrite: Overwrite data sequentially from the start to the end of the file.
Partial overwrite: Overwrite data to a part of the file only.
