Mac Quick Look not enough? Unfold adds 260+ file formats

Mac's built-in Space key preview feature (Quick Look) only recognizes certain formats like images and PDFs, and it's powerless when faced with archives, folders, 3D models, and other file types.

Some files can be previewed, but the experience isn't great—for example, previewing code doesn't support syntax highlighting.

Newly launched this week, Unfold is a single app that extends Space key previews to over 260 file types:

LaTeX formulas, archives, e-books, subtitles, 3D models... they all open in a split second with one press of the Space key.

No need to open an editor, no need to extract, no need to install a pile of scattered plugins or apps—just press the Space key to view files with ease.

If you're interested, head to the LIZHI.SHOP software store to learn more about and purchase Unfold—a genuine license with lifetime use.

Check folder sizes in seconds

In the past, to get a rough idea of what files were in a folder, you had to open and rummage through them one by one, which took forever.

Now with Unfold, just select a folder and press the Space key once, and the file list and size info appear instantly.

You can also expand subfolders layer by layer—no matter how deeply a large file is buried, it won't escape your notice.

Filter out useless files / folders, free up disk space... everyday file handling becomes more efficient and convenient.

Preview archives without extraction

You've downloaded a 2GB archive, and extracting it rashly without knowing what's inside can easily unleash a pile of useless or even dangerous files.

With Unfold, formats like ZIP, RAR, 7z, and TAR can be previewed without extraction, with every file's name and size clear at a glance.

See clearly first, then decide whether to extract—safe and worry-free. Once you've used this feature, there's no going back.

Code highlighting with copy support

Opening files like .py, .json, or .yaml just to confirm a config constant or change a function name—and you still have to launch a heavyweight IDE?

Unfold supports syntax highlighting for 60+ programming languages, and lets you select and copy code snippets directly.

Glance at the structure and configuration before modifying code, and save yourself the waiting time of opening an editor countless times.

Users can also customize the preview effect, adjusting settings like the font, font size, line numbers, and transparent background.

Formula typesetting you'll love

No matter how well written a Markdown document is, previewing it directly still gives you a rough, unrendered result; and when you don't have a LaTeX environment installed, even taking a single look at a LaTeX file is a hassle.

Unfold renders both inline and block-level LaTeX formulas directly, laying out mathematical expressions nice and clean.

It also thoughtfully generates a sidebar table of contents for Markdown, so you can jump right to any heading.

Anyone who often needs to write papers, read documents, or look up reference material is sure to love this feature.

Rotate 3D models with ease

Received a .3MF or .STP model file—do you really have to go out of your way to install professional editing software just to take a look??

Unfold lets you rotate, pan, and zoom 3D models with a press of the Space key, smooth and lag-free.

Checking parts, confirming structures, quickly running drafts by clients—all easily done right in Finder.

From now on, designers' and engineers' computers can skip one more heavyweight app that would only ever be opened for a quick look.

Final thoughts

In addition, it can preview a whole wave of common formats, including subtitles, e-books, web archives, Jupyter notebooks, app package info, and more.

Download it and give it a try to see whether your commonly used file formats are supported!
