To start, please note 34KB isn't much space at all. That phone has a minimum of 12 megabytes and a maximum of 8 gigabtyes depending on when you got your phone.
But just for size comparison, 34 kilobytes = 0.033203125 megabytes so you have plenty of space, those kilobytes mean nothing.
I don't personally own a Nokia phone, but from what I hear, all of
their phones have software on them called Lifeblog, it stores all of
your photos taken, and all of the calls you have made on your phone and
arranges them in a time line, this ends up taking up a lot of space and is a cause for many of the memory related problems.
Possible Solutions:
First:
Backup anything you want to keep with
Nokia PC SuiteThen:
Reset your phone to factory default by either typing *#7370#
OR
Holding down 3 * green whilst switching it on.
Be wary when restoring any backup you have, being this will restore anything that your Lifeblog contains, reverting the problem.
And a final solution
Download "Y" browser
hereInstall it on your phone via your Nokia PC Suite.
Launch the YBrowser application (probably from new folder called DrJukka.com):
Locate the C: drive and open it:
Locate the Data folder:
Locate the Lifeblog folder:
Select
Options,
File and then
DeleteOnce the folder is deleted launch Lifeblog and select
Update Timeline.
Hope one if not all of these helped =)
