I know that in some circumstances some custom files with same filename can be put on a different-than-ROM drive and the system will read the files from there instead of ROM. For example, on a N73 device I put some .ttf fonts on /resource/fonts folders created on the miniSD card and after reboot the system used that fonts only (was for extended glyphs on particular language when reading SMS or email).
Recently I have applied the same principle on a N8 with Symbian Belle on it, related to keyboard layout files, where I modified some peninputblahblah files from Z:/resource/plugins and put them to C:/resource/plugins. That also worked perfect.
However I tried to do the same keyboard layout workaround on a Symbian Anna, but didn't worked.
My question is -- is there a system config that tells the OS to look preferentially on one or other drive for a given file ? I mean a general rule (principle). The N73 is rather old and worked, Anna is newer and didn't worked, Belle is even newer and worked again, so I am a bit confuzed here.
(have not tried the microSD font substitution on Anna, though)
Thank you,
