applications filling up C: drive, why ?

Hello,

Had completely reflashed my phone, and noted that following this i had some 140 MB free on C: drive.
Then checked on my Ovi Store account and double checked that all applications must install on E: drive ( mass memory ).
Now, after installing some apps, and having two e-mail accounts and 6 rss feeds active, i notice that free mem is lower, towards 115 MB.
In between, i had deleted the MS Communicator, and Social ( have no interest in FB or tw ), but still no avail, as soon as i install any new app, C: drive is lowering free space.
Before reflah, i was as low as 10 MB hence the need for refresh.

Now, is anyone that is aware of this ? how can i avoid again filling up again the C: drive ? is there a setting for this that i missed ?
Is there any file(s) that can be safely deleted on C: ?
any comments appreciated..

best regards,
radu

i do not think that there is any file that you can delete on C:, or move.. anyway, not one fiel that is big enough.. .log or .txt file are not interesting from this point of view.
i really need something that makes applications installing on E: there is enough space, is there any other setting otherthat one found in Store app ?

happened to me my cdrive says It's low I'm getting fed up and bored of the n8 I also put on An App called Ramblow try that? I also look in my Cdrive and nothing to say It's full up?? also I deleted all my videos and pictures on the phone and backed up.
