How to disable preview for some types (EPS) of files thumbnails in Mac finder?

Solution 1:

You need to disable /System/Library/QuickLook/EPS.qlgenerator. You can rename it to append .backup to that & 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

& 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"
)

Solution 2:

Instead of modifying your system, use a Smart Folder to filter out what you're working on.

I'm no artist by any means, but there are times I need to utilize Photoshop or Illustrator to modify some images. Since I need to work with PSDs which also get thumbnail previews, I create a Smart Folder that searches that folder with limited scope in criteria.

For example, in the image below, I created one (for this answer) that searches my Desktop for all images. You're not limited to what you can search for - filenames, extensions, types and even meta data!

I keep these smart folders on my desktop or in a place with convenient access. Like in your scenario, I'll put the smart folder at the "head" of the images folder with all of its sub folders. I can then open it and just get all of my PSDs without the clutter of everything else.

How to create a Smart Folder

Simply click on File in the Finder menu bar, and select New Smart Folder. Just set your search criteria and away you go!
