what is the path the file system location where SMS messages stored? Where in the file system are SMS messages stored? plese list the path
In CM11 (Android KitKat) when using stock messaging app the database file is located at:

/data/data/com.android.providers.telephony/databases/mmssms.db

Note that it's not a text file, it's a sqlite database file which needs to be accessed via sqlite-capable front-end (such as sqlite command line client).
