Script Debugger is a good Mac OS X citizen, and does not heedlessly install files in places where it’s not supposed to. Still, it does install files in a variety of locations, and you might wish to know where these are and what the files do. So here’s a list.

~/Library/Components

Script Debugger installs Script Debugger.component here. It implements debugging, by means of an OSA language which you can see listed in the Language popup menu in any Script Debugger script window (or any Script Editor script window, for that matter).

~/Library/Caches/Script Debugger 4.5

Script Debugger maintains caches of application dictionaries here. These caches mean that Script Debugger can open and access dictionaries much more quickly.

~/Library/Application Support/Script Debugger 4.5

The Clippings folder is where Script Debugger gets the items to populate the Clippings menu and the Clippings inspector. The Scripts folder is where Script Debugger gets the items to populate the Scripts menu and the Scripts inspector. The Script Libraries folder is where Script Debugger will automatically look for a library to attach to a script. You can modify the contents of these folders.

Script Debugger automatically populates these folders to start with. If you need Script Debugger to perform this automatic population again, move the ~/Library/Application Support/Script Debugger 4.5 folder aside (for example, drag it to the desktop), then quit Script Debugger and start it up again. Now you can move your own materials back into place if desired.

~/Library/Preferences

Script Debugger keeps one preference file here, com.latenightsw.ScriptDebugger.plist. This contains a lot of information, including state information for various windows, so be aware that if you throw out this file, such information will be lost.

Also, Script Debugger maintains the Script Debugger Preferences folder, which contains the default document that is opened when you create a new script window.
