How To Clean Up Nokia 5233 Phone Memory?

Could anyone tell me why my mobile phone memory is showing being occupied?

• I have Nokia 5233. My phone memory shows being occupied irrespective of nothing. You can see the this pic. http://i.imgur.com/xybUW.png My sis files, messages and other files occupies only 10-12 mb. Rest of the 70 mb occupies by other files. What are these other files ? How do i get my this memory back ?

• Answer:

  'other files' can be apps, installation files for apps, maps data, messages, web browser cache, etc. So go thru things like ur browser and in the options, delete cache, cookies, history, etc. Open messaging, settings, and change the default message saving location to memory card. Go to ur app manager and delete any apps and themes that u downloaded and saved to ur c drive. And look in ur maps settings to see if u can change the default save settings because every time u view a map, it saves it. If all that still doesnt help, a hard reset might be ur only option but thats a drastic last resort that will format ur phone and delete everything.
