Got an Apple, Mac or iOS tech concern? We have the response. This time, we respond to a viewers’s question about file expansions in OS X. Some people like ’em, some people don’t – once, Mac documents didn’t have extensions whatsoever! How do you establish whether they’re shown or not? Below’s the simple solution.

Question

I recently switched to a brand-new Mac, as well as I’ve seen something odd taking place: when I save data or take screen grabs, they often be missing their documents extensions (. txt,. png, and so on), which was never ever a problem on my antique machine. Just how do I obtain them back?

Answer

There are a few things you could do to make certain that your documents show their expansions. The most basic is to go to the Finder > Preferences food selection, select the Advanced tab, as well as inspect the ‘Program all filename expansions’ box. All your documents extensions need to now show up – easy as pie. Conversely, if you intend to conceal your file expansions, merely uncheck the box.

You could also prefer to reveal your file expansions on a per-file basis. When you’re conserving a file, you’ll often see a checkbox that lets you prefer to conceal the file expansion, although this choice might not appear if you’ve activated the universal ‘Show all filename extensions’ preference. Furthermore, if you intend to make it possible for or disable the extension of any existing file, click on the data, then choose the Obtain Information option (either from the Documents menu, by right-clicking, or by hitting Command + I), under the Name & Extension area, there’s a ‘Conceal expansion’ checkbox you can transform on or off.
