Recent File List Thumbnail Cache Problem of PS CC 19

Our company use Photoshop CC to retouch the customers photo and some sensitive information such as id card copy, bank and credit card information.

Due to the privacy policy of our company, we don't want PS to automatically cache everything after it opened. We've tried setting Performance->Cache Levels to 1, but not success. It always return back to the value 2 after PS restarted.

Then we set the File Handling->Recent File List Contains to 0 files. This hide the cache that PS created and nothing shown on the first page when PS started. However, when we changed this value back to 20, we discovered that all the opened file doesn’t shown on the first page were appeared again even if the image files have been deleted. It seems that PS creates the thumbnail cache without our knowledge and we cannot take control with it.

We already know that we can delete the whole recent file list from the menu, but if our staff forget to delete it, the next staff who use PS can view all these sensitive information which we don’t want to happen.

So we would like to know is there any way to force PS not to cache anything?

Also, where is the location of these cached photo and thumbnail saved and how to delete these file manually?

Until a technician or product manager can offer a solution, I''m hesitant to touch internal photoshop thumbnail caches.

So I did think of a workaround that I posted in the Adobe Photoshop forums.

If you use the File > Export command, the exported file will not show up in the recent files list because it is saved, but not opened.

You can then turn off Layer visibility when you save out your Master file and you have a blank thumbnail in Recent Files. If you need further edits, just follow the above steps.

The Exported files then should be set to open in another viewer program, just not Photoshop or any other Adobe program.

It should keep the thumbnails out of Photoshop and assure confidentiality.

The trick is to keep anything you don't want others to see in a password protected archive.

You will have to explain the procedures if you need editing help.
