Group nameName of group
It needs unique in the groups and different from any other layer name.

Group ID

Freely-selected positive integer is determined to identify group. It has to be
unique in the groups.

Parent group ID

When the group is subordinate to another group, the parent group ID iswritten. Without the description, it is treated as a group of the most significant
position.

Sublayer ID

ID numbers of layers belonging to this group are described as comma
separated.

Initial display

When the group is off-displayed in the initial state, "hide" is written.
When the group is off-display, the subordinate layers are all off-display.
("Hide" is unnecessary to write in initial display of layer setting lines.)*Each layer out of groups is treated as single and the most significant position.

About reference of relevant files
Layer information and marker relevant files refer to each file due to following rules,
When the relevant file is designated by absolute path:+ The file designated by absolute path is referred direct.
When the relevant file is designated by its name:1. when the data is an octa file, the referred file is;+ at first priority, in octa file.
+ at second priority, in the same folder as the data file.
2. when the data is NOT an octa file, the referred file is;+ in the same folder as the data file.

About handling the relevant files in octa file
A relevant file in octa file is opened with standard application after it has been output
in temporary folder of system standard at once.
<Output location>[Standard temp folder of Windows]/OCTAS/[octa file name]/[relevant file name]
A temporary relevant file is opened with "read-only" attribute to prevent from editing.
Editing and/or saving the file are available after saving it as a new file and naming it
in user area in the application.
(The same operation as a file in zip is opened in Excel or etc.)
Output relevant file in temporary is deleted at the time of quitting OCTAS. However,while the temporary file is opened, there are cases where the file remains (depending on
application).
As this elimination process of temporary relevant files is done at the every time ofquitting OCTAS, the remained file is deleted at the next quitting time.
