Zip Files – 4GB Limit?

It appears that originally, Zip files had a 4GB limit, and the software that is part of the Mac OS is only able to open files under this size

If you have zip archives over 4GB then you will need software capable of extracting this, thankfully there is The Unarchiver, a free app fromĀ http://wakaba.c3.cx/s/apps/unarchiver.html

Download and install the App into Applications by dragging it there

For ease of use I will put the icon in the dock, then you can just drag a zip archive to the icon to begin extraction

Show Hidden Files

You can see hidden files by in the Terminal, but if you wish to display them in Finder then you will need to do the following

Open Terminal and type

defaults write com.apple.Finder AppleShowAllFiles TRUE

then

killall Finder

Open a Finder window and you will see the previously hidden files, if you wish to switch back then you can do the following

Open Terminal and type

defaults write com.apple.Finder AppleShowAllFiles FALSE

then

killall Finder

Open a Finder window and all the unhidden files will now revert to being hidden again.
