No ".open" option in version 3.7.17 2013-05-20
I did so and can read text/words does make sense, but there was no "SQLite format 3" text on the head...

Does this mean that 
1) the db is an sqlite db (why could I not get any .table nor .schema? it says file is not a database of it is encrypted
2) the db is not an sqlite db but its encoding could be read with "strings myfile.db | head"?

I also run "strings myfile.db | more" and seen 
3) What would you recommend me to get the schema of this db and manage to read it?
4) Can I dump somehow these strings to a kind of csv textfile?
