Un-Zipping the File
Windows: Right-click or hold the zip file and press "Extract All." Follow instructions to extract files into same folder Zip file is in.
Mac OS X: If you’re using OS X, all you have to do is double-click the zip file. The files will be extracted to the same folder as the zip file.
Downloading to a Mobile Device
Once the zip file is downloaded, unzip it and access the mp3 audiobook files with mobile device apps.
Apple iPad, iPhone, iPod
If you use iTunes for accessing content on Apple mobile devices, audiobooks can be downloaded and unzipped on the main desktop or laptop and moved via “drag and drop” into the corresponding iTunes Library section, where they can be synced with your Apple mobile devices.
If you do not use iTunes on a desktop or laptop computer to sync with your Apple mobile device, and wish to directly download Zip files and access their contents on your Apple mobile device, then the following free app is suggested:
Bookmobile Audiobook Player – for receiving, unzipping, and MP3 listening within the app, plus the “Open In” function to any other compatible app installed on the device. Bookmobile can receive direct downloads, as well as file transfers via USB, Dropbox or Wi-Fi network.
To download to Bookmobile from a link or email attachment, hold (not tap) your finger on the link or attachment, and a menu will appear. On that menu, you can select “Open In” and then select Bookmobile. Once you have downloaded to Bookmobile, it will automatically go into folders with the same names as the original Zip files, making it easy to manage your audiobooks. All folders and files are stored for easy access, and can be exported to other computers if desired.
For MP3 AudioBook Listening on iPad/iPhone/iPod (free apps):
Bookmobile – Play MP3 audiobooks from direct downloads
iTunes Music – Play MP3 audiobooks (synced from iTunes only)
Android Tablet or Phone
Android devices have centralized file storage, and the same files can be accessed from multiple apps on the device. Downloaded files go the “downloads” folder, where they can be accessed, moved etc. If your Android device is not set up for downloading zip files and accessing their contents, the following free apps are suggested:
Android File Manager (for Android OS 2.0 and up) – Can access, unzip, manage and open audio files in most compatible apps installed on the device. Unzipped files go into a folder with the same name as the original Zip file, making it easy to manage your audiobooks.
AndroZip File Manager (for Android OS 2.0 and up) – Can access, unzip, manage and open audio files in any compatible app installed on the device. This app has a few extra options not available in the basic Android File Manager app. But it may display more ads than you would like, unless you opt for a paid version.
For MP3 AudioBook Listening on Android (free apps):
Music Player – Comes with Android. Not bad for continuous album/audiobook playing
Smart Audiobook Player – Full featured player for continuous album/audiobook playing.
