WHERE do I put (install, add) third party atn and asl files?
I see some in root>application?CS4>presets>actions
also
User>lib>applicationsupport>adobe>CS4>presets
Thanks a bunch.
I don't know if the reason for doing this is so that we don't lose our personal Actions etc. if the Application itself is un-installed – but it might be.
If you are the only User of Photoshop on your machine you might choose to put your own saved Actions and Styles in the equivalent folder in your Application/Photoshop folder as we did in earlier versions but it does seem that Photoshop can find them in either location but looks first in the User location by default; but subsequently goes to the last location to which you navigated.
I think that having Adobe-installed Presets in one place; and User-saved Presets elsewhere is confusing.
If PS were uninstalled, wouldn't it take User folder also?
I don't know the answer to that. You might like to test it to see?
But if you back-up your whole System HD, you will have copies of everything there.
In any event, I rather have to deal with a corrupted user Library folder than a root-level library folder. Just my preference.
