To free up phone memory in n86
1. delete any known large attachments from Messaging and/or Nokia Messaging
2. delete any direct downloads you've done
3. remove any trial applications you've installed to 'Internal memory'
4. use Y-Browser/xplore to delete the '\cache' folder on C:/system (deleting the cache from inside Web isn't as reliable)
5. (if a Google Maps user) use 'Options | Tools | Reset' - this frees up memory used for cached maps
6. again in Y-Browser/Xplore, delete 'C:\system\temp' , there are sometimes Megabytes of .SWF (Flash) files here
7. delete the ‘dmgr’ folder in C:\System
8. change your default ‘Messaging’ memory to either the 8GB inbuilt storage or a Memory Card. To do this, enter ‘Messaging’, hit Options>Settings>Other>’Memory In Use’
9.Open the Ovi Store application settings and make sure it is set to install applications on your E: drive. To do this navigate to Options>Account>Settings>Installation Preferences.
10. go to C:\data\wscache thn call logs n delete all...do the same 4 msgs n contacts..it does nt delete them from your phone..may be its a archive or something.
11.If you use POP email, which you shouldn’t since there is IMAP, then go into your mailbox settings and set it to enable POP for email that arrives from ‘Now’ on, this will reduce the number of old emails it downloads. I know this seems petty.
