A quick guide to using the addon manager in FS2 Utilities. Page Two
and how to create jr2 files for distribution.
This is the screen that appears after clicking on the add button.

Step Five: This is the window that lets you start adding all the files you need to create your jr2. As you can see from the screenshot above, you use the righthand window to navigate through your Fishsim2 folder to wherever your files are that you need to add. Remember to add all the files that you are using in this addon you are making, do not assume that people will have things loaded from previous addons you may have created. Play safe add everything. The only exception to this is if any of the files you are using came with the original FS2 download. ( sorry, I got diverted there :)))) right where were we, yes as I was saying you use the righthand window for navigation through you fishsim folder, above you can see that I have gone to the species folder in fs2 and found the folder that I created earlier, which contains the species that I am going to add to this venue. And you can see that by highlighting the folder that I want in the righthand window, everything in that folder appears magically in the lefthand window.
Step Six: This is where we start to select and add our files to the jr2, you do this by moving across to the lefthand window and highlighting the files that you are going to add, you can do this one file at a time which would take forever, or like I have done in the screenshot below, by using the left mouse button and holding down the shift key to do a multi select. This saves a lot of time if you have a lot of files to add, when you have highlighted all the files in this folder that you want to add, click on the ok button in the top righhand corner.

The window that will appear is on the next page..
