Can someone tell me how to access the datafiles if I install the application on the memory card. (I use a Nokia 6600). The app runs fine when I install on the phone memory. However due to space limitations I have to put the application on the memory card. The application runs but stops without any warning when I run any activity involving file read & write.

Do we have to use some drive letter like D: or C: etc. Roll Eyes

Try to use drive letter. You can also check disk space before read or write using SysUtil::DiskSpaceBelowCriticalLevelL method.

C: is phone memory
E: is memory card
Z: ROM

Are these drive letters universal
Thanx juuseri,

Are these drive letters universal standard for all series 60 phones or only for Nokia 6600.

At least currently all series 60 phones implement the drive letters this way. However, it could change some day. So I propose using the PathInfo class (part of platformenv.lib, pathinfo.h) to get them. Use RomRootPath(), PhoneMemoryRootPath() and MemoryCardRootPath(). From there you can extract the drive with TParse. e.g.

Code:

TFileName drivePath( PathInfo::MemoryCardRootPath() );    
fileName.Append( TParsePtrC( drivePath ).Drive() );
fileName.Append( KMyFilePath );

D is the phone's ram drive, which is not persistent across reboot.
