I am using Nokia E62 and have installed a application like FExplorer.
I can see some of the files in the ROM drive
under z:\resource\
WlansettingsUi.r01
WlansettingsUi.r39
WlansettingsUi.r59
WlansettingsUi.r70
&
WEPSecurtitySettingsUl.r01
WEPSecurtitySettingsUl.r39
WEPSecurtitySettingsUl.r59
WEPSecurtitySettingsUl.r70
If I am not wrong these files are somewhere related to WiFi.
But i cannot see the reference of them on the handset.
If the files are unwanted, hope they will not cause any problem during my regular use.
