The J executables j.exe and j.dll are installed in the main J directory, for example, c:\j406.
The following system subdirectories are created by the J installation:
System\Main | Main libraries and utilities |
System\Packages | Packages (e.g. Stats, Printing) |
System\Classes | Class definitions (e.g. Grid, Plot) |
System\Extras | Various system utilities |
System\Examples | Various Examples |
In addition, two other subdirectories are created when J is installed:
User | User Definitions |
Temp | Temporary files |
Subdirectory Addons is created when one of the J Addons is installed.
