Question

Install4j has the system variable sys.docsdir that will create a data directory in the proper place. But I can not find an action to add to the installation that will create an empty directory. What is the action? If I need to create custom script, a sample would be awesome.

Answer 1

The installer variable sys.docsdir contains the path to the user-specific “Documents” folder on Windows, it does not create a directory.

To install files into a subfolder of the sys.docsdir directory, add a new root under Files->Define distribution tree with the name ${installer:sys.docsdir}/myfolder and add the files below that folder.

To install to a folder that is resolved at runtime, the name of the installation root can contain your own installer variable, like ${installer:myDataDir}. In that case, you have to define that variable (for example with a “Set a variable” action) before the “Install files” action runs.
