As you likely know, when using Finder (including any OS X file dialogue from with an application, and files attached to emails) selecting many common file types and hitting the SPACEBAR will often present a QuickLook preview of the file.
Here’s how to get add this feature for most common (and not-so-common) archived file formats. The currently supported archive formats are: ZIP, TAR, GZip, BZip2, ARJ, LZH, ISO, CHM, CAB, CPIO, RAR, 7-Zip, DEB, RPM, StuffIt’s SIT, DiskDoubler, BinHex, and MacBinary.
2) Install BetterZipQL (these instructions are from the macitbetter.com site)
Unpack, and copy the BetterZipQL.qlgenerator bundle to your /Library/QuickLook folder (if you want to install it for all users on your Mac) or to the ~/Library/QuickLook folder, this is the Library/QuickLook folder inside your user folder. You may need to create the QuickLook folder inside ~/Library first.
The Quick Look framework will need a little time before it realizes that a new generator has been added. If you are impatient and not afraid of using the terminal, you can execute the following command to make the Quick Look framework reset immediately:
or you could restart the Finder. Or logout and -in again. Or restart your Mac. Or take a nap. You choose.
- Toggle whether you like to see hidden files and package contents.
- Choose which columns to display.
- Toggle whether the header section should scroll out of the window or be kept in place.
You can set the various options directly in the Quick Look pop-up. Just click the Preferences button in the upper right area. Set your options and click the button again to hide it.
When using QuickLook on archive files, you’ll now see a QL window like this:
