I cannot believe how difficult it is to find this information. It should be a quick search in the regular Help system.
I'd really like to find the file locations for Illustrator CC and Photoshop CC too, because I need to update my Pantone libraries, but every place I can find to save them does not seem to be the default location, so I end up with a really long dropdown menu of strangely duplicated library names, and I have no idea how to clean it up or where the program is looking to give me that list.
As far as I can tell, the default libraries are located whereever that first set is. The lower sets must be somewhere else, but I don't know where, because I've deleted all Pantone sets but one that I could find, but I can still see them (and the other non-pantone color books) duplicated in the lower sets.
Please help! Also, Adobe, if you see this, this information should be READILY and EASILY found through the main Help menu in any Adobe product.
