In Standard-SQL database language, there is the concept of 'schema'. A schema is a grouping of tables inside a database. (This resembles the directory (=folder) of a filesystem enough that in my database I sometimes type 'mkdir' instead of 'create schema').

But your mention of cat.txt, makes me think you actually want to store text (from text files). That's possible but it has little to do with 'folders'.

As always with database design, future queries should be specified, not so much (often vague) ideas about storage.

Does cat.txt also contain table-like data? Or is it free-form text?
