@gdon_2003. Nice tip about the Data Dictionary. Didn’t know that. I found the directory by searching AppData.
To be even more specific, the tools are in the Carbide Create\tools directory. In there custom tools libraries use the same name as the file except there is a + instead of a -.
I was looking for this file because, I design on a different computer than I use for the shapeoko so syncing my tools files is important. I posted about this a few days ago. (Carbide Create Tools Library), no need to read it. Between this and @gdon_2003’s reply you have everything you need.
