How can I invoke JDiskReport for a specific folder??

You can set the runtime argument path. JDiskReport will then skip the start panel and scan the given path. In a command line invoke: javaw -jar -Dpath= jdiskreport.jar Note that the user path should be embraced by quotes on Windows platforms. If you have installed a Windows edition of JDiskReport there’s a shortcut for the above: you can select a folder in the Windows Explorer and then run JDiskReport from the Explorer’s popup menu.
