Back in December, I wrote about freeing up space on your hard drive. The one thing I neglected at the time? All of those pesky unused language files. Enter a neat little app called Monolingual. Current version requires a 64-bit capable Intel-based Mac running at least OS X 10.7, but there are older versions still available that will run on OS X 10.4. How much space can you free up? Depends on how much software you have installed. Would you believe 3.86 GB on my iMac? And no, I didn’t get rid of everything except American English. I do speak a couple of other languages, so I kept those, along with all versions of English.
One very big caveat! Some (most) Adobe products don’t like you messing with their files. Eliminate one stinking language and it may decided it is damaged beyond all repair and you’ll need to reinstall. It’s a documented problem. I found out the hard way a few years ago. I was not happy. The solution? Before running Monolingual, open preferences and add all of your Adobe products to it. Easy to do, and I guarantee that it will save some serious cussing.
If you want to play it safe, you can always check “Move language files to trash” instead of out and out deleting them, although I’m not sure if the Undo (Command-Z) would actually put them back. Never tried it. Oh, and I didn’t save quite as much space on my MacBook Air. I only saved 3.25 GB. Yep, on an Air, that’s a significant amount of space. So far, I haven’t run into any problems from missing language files.
