+# File type info
+
+Proposed file types (ideas):
+* General:
+	* `.list` - a list of strings
+		* a list of strings placed in separate lines
+		* doesn't count empty lines
+		* gotta think about comments within
+			* maybe the standard `//`?
+			* maybe `;`, etc at the beginning of line?
+	* `.map` - a map of key-value pairs
+		* primarily for saving values of actual objects' parameters
+		* can be used for other purposes as well
+	* `.class` - a class file
+		* parent object reference
+		* references to `.list`
+			* primitive variables list
+			* object reference list
+		* references to maps (see below)
+			* for constants
+			* for static variables
+			* for methods
+* For handling objects:
+	* a folder for keeping static class definitions
+	* a folder for keeping object instances
+	* a ledger for keeping track of object instances
+		* and maybe relations?
+* For future reference:
+	* `.vob` - visual object-batch
