I'll post instructions on how to transfer audio files from ZTE F160 to computer with USB cable as soon as I find it. You may use these alternatives for the meantime.
Using a memory card:
The ZTE F160 has a microSD memory card slot. If your personal computer is compatible with that type of card (Most laptop computers are so-equipped), you should be able to save a music file
The ZTE F160 is Bluetooth-enabled. Bluetooth is a wireless protocol which lets you connect your cell phone to computers, headsets, car kits, etc. If your computer is also Bluetooth-enabled, simply connect both devices and transfer your audio files from your computer to your ZTE F160.
Through a 3G Uploader:
If the above-mentioned methods do not work for you or if you prefer not to buy new accessories, you can still use one of the numerous free "3G Uploader" services available online. A search on Katapulco should retrieve plenty of them. 3G uploaders are easy to use: Transfer your own music on their web site and they will return a temporary web address. Pointing your ZTE F160's web browser to that address should download the free ringtone. source
