How to disable preview for some types (EPS) of files thumbnails in Mac finder? I am stocker and draw tons of images in Adobe Illustrator. All images are being saved in pair of EPS and JPG format. I updated to Catalina on my Mac and the Finder now shows preview for both EPS and JPG Thumbnail and it is impossible now to work for me with tons of duplicated files visually.  Before my Finder is shown only preview for JPG and all was polite and good. 

I attached how I what to see all in finder. Buy the way, all old folders still as I want, but all new files created - there is .eps file preview
You need to disable /System/Library/QuickLook/EPS.qlgenerator.  You can rename it to append .backup to that &amp; then rename it back to original to restore it.  

OR you can simply make a copy somewhere else and delete this quicklook generator. 

You may need to run

qlmanage -r 


after that.

The way I reached there is:

mdls /path/to/some/epsFile/pwrdLogo.eps   -name kMDItemContentTypeTree


&amp; then searching the output of 

qlmanage -m 


for  one of these

kMDItemContentTypeTree = (
    "com.adobe.encapsulated-postscript",
    "public.item",
    "public.data",
    "com.adobe.postscript",
    "com.adobe.encapsulated-postscript",
    "public.composite-content",
    "public.content"
)
