Most of My Presets Did Not Migrate to Photoshop 2020?

When it comes to presets and their locations, there are two of them!

More on that here:

In the case of actions:

Mac:

Applications/Adobe Photoshop CC 2019/Presets/Actions

Users/username/Library/Application Support/Adobe/Adobe Photoshop CC 2019/Presets/Actions

Win:

C:\Program Files\Adobe\Adobe Photoshop 2020\Presets\Actions

C:\Users\Username\AppData\Roaming\Adobe\Adobe Photoshop 2020\Presets\Actions

(Note: The AppData directory is hidden by default)

Hope this helps!

After upgrading to Photoshop 20.0.8 on my Mac this week; Photoshop (for the first time since the past 4 installations/updates) loaded all my presets correctly. If you are still having this issue like I was, I would suggest upgrading to the latest version as it seems to have fixed that issue. 

I just installed Photoshop CC2020 on my 2nd computer - same thing (so it probably was not a bad install on my main computer).

My second computer is a 2015 MacBook Pro running Catalina 10.15.1

In past version upgrades I have always copied my personal presets manually from the various previous version presets folders in the Finder. That is not working at all with CC2020? They all copy fine in the Finder, but they do not show up in CC2020? Oddly, I can Import presets into CC2020 palettes from the old CC2019 preset folders and they show up in Photoshop, but those imported presets do not show up in the CC2020 preset folders in the Finder? I just imported some of my old Gradient presets on my second computer into CC2020 from my old CC2019 Gradient Presets folder and they show up in Photoshop, but there is not even a "Gradients" preset folder in the CC2020 installation? ...so where is it storing these???

On the plus side, both my computers running different Mac OS versions are experiencing the exact same messed-up behavior - so it is not just a fluke on one system.

Hi, Try the following

For Styles:

Open the Styles panel (Window >Styles)and click at the top right

To load the old default Styles - choose Legacy Styles
To load your own choose Import Styles and navigate to the folder where you have put them (it should open in Adobe Photoshop 2020>Presets>Styles)

For Gradients :
Open to the new Gradients panel and click at the top right.
To load the old gradients - choose Legacy Gradients
To load your own choose Import Gradients and navigate to the folder where you have put them (it should open in Adobe Photoshop 2020>Presets>Gradients

For Patterns :

Open the Styles panel (Window >Patterns)and click at the top right

To load the old default Patterns - choose Legacy Patterns
To load your own choose Import Patterns and navigate to the folder where you have put them (it should open in Adobe Photoshop 2020>Presets>Patterns)

All my patterns, actions and styles are gone... removed, deleated! This new installation went into ALL my older folders - and deleated everything. I am so pissed, everything that I made during all these 22 years is gone forever. Deleated! 
After total of 12 hours searching on 4 harddrives I finally contacted the "support" and told them that I want atleast the old Styles and Patterns - and I have been waiting almost 2 hours now for the "specialist" to even take a look at my request. 2 hours - and no one replies. 
I really really do not like Adobe, they are the worst of all software-companies that I had to do with. 

I have a similar issue. Since upgrading to the latest version on my Mac, the new Photoshop 2020 seems to be falling apart. It won't import any presets even though I know the presets are in the preset folders for Photoshop 2020. When I try to import them, the folder shows as blank but i can see the presets in their folders if i use Finder. These are my presets that I have used in Photoshop 2017-2019 and I even tried placing the original preset files I purchased in the styles folder but it still shows blank. And it keeps freezing on one image (i.e. the same file/image showing on each tab when I click through the tabs). AND generate assets no longer save to the dpi of the document. It's just 72dpi now no matter the document settings. I use Photoshop for my Graphic Design class at uni and the week I've had since upgrading to Photoshop 2020 makes me want to ask Adobe for a refund because at this point there's more not working than working in the latest version. It seems you either have to contend with the program crashing or the features not working. So you're paying for a product that doesn't work.
