Okay, here’s my experience with “raw preview” from start to finish, shared in a casual, blog-like style:

So, I wanted to get a quick look at some files without actually, you know, opening them in their proper apps. Think of it like peeking at a document without fully committing to reading the whole thing.
I started by poking around my file manager. I use a Mac, so that’s Finder for me. I remember there was this thing called “Quick Look”, but I’d never really messed with it much. Turns out, I was missing out!
My Little Experiment
I selected a random image file – a JPEG, I think it was. Instead of double-clicking it to launch Preview (the image viewer app), I just hit the spacebar. Boom! There it was, a nice big preview of the image, right there in the Finder window.
Then I got curious. What else could I do? I selected a text file (.txt) and did the same thing – spacebar. And yep, the text popped up, no need to open TextEdit. It even worked with a PDF! I could see the first page without firing up Adobe Reader, which, let’s be honest, can be a bit slow sometimes.
I then tried navigating through a bunch of different files – images, text documents, even a spreadsheet. Just using the arrow keys while the preview was open, I could flip through them. Super handy for quickly browsing a folder.

- Select a file.
- Hit the spacebar.
- Use arrow keys to navigate (optional).
- Hit the spacebar again to close.
It’s such a simple thing, just hitting the spacebar, but it genuinely made my workflow a little bit smoother. I did all of this is in less than 5 minutes!
It’s now my favorite method, and one I intend to keep using going forward!
