Other directories with > another number can be created ? This is the oFono cache for SIM filesystem files. Essentially files = that are not writable by the user on the SIM are cached on the = filesystem to speed up initialization time. The suffix (e.g. -3) is the = SIM phase. E.g. 3 is 3G/USIM, 2 is 2G/SIM. > > I'm wondering this because I want to put this directory and files in a > separated partition of 1.3MB and put my root partition read only.

I began to read the source code but > maybe you can tell me some hints. oFono caches both incoming and outgoing SMS here as well. For = reception, the SMS store is used to cache reception of multi-part SMSes, = e.g. ones longer than could fit into one payload. For outgoing, the SMS = is cached here until it has been sent / delivered. Regards, -Denis --===============2353833733844007933==--
