The best way to free up space on your device is to back up your data. To do this, you need to have installed an application that syncs between your phone and a PC. For Android phones, this is no simple matter due to the variety of models and phone manufacturers.
Below is a list of popular applications for syncing between a PC and an Android phone:
Which flavor of Android?
If your phone is a less well-known brand, such as an LG, locate your installation CD or browse the manufacturer's web site for the sync application - assuming the manufacturer has a web site, that is!
Samsung Kies
You download and install the Samsung Kies application on your PC and connect your phone using a USB cable. The application lets you transfer music, photos, videos and other files from your mobile phone.
You can also back up copies of your most important data such as your calendar, SMS messages, notes, and more.
In addition, some phones let you update your Android version using Samsung Kies.
Kies Air

From there, from there you can very easily copy images, videos, music and more.
