What sort of project does your application create? That will determine what the save methods need to do.

My app is a Structural Design software, and get some text data by windows form and after analysis and design, produces outputs.

What information are you trying to save? If you want everything in one file then you need some sort of identifier before each record so that you know what sort of data it is. Alternatively you could use a local database like SQL Compact Edition, or SQLite.

If you are using a database, there is no need for saving because updates are applied automatically.

New: Create an empty database (optionally with default tables and values) and open/connect that
Save As: Create a copy of the current database and open/connect that

If you want your application to behave similar to other file based applications but use a database engine for reading and writing, just use database files with local storage and an API like ODBC. Otherwise, you would have to setup a database server.

Are you trying to implement your application to behave like visual studio solution file?

If you are familiar with engineering software, you will have several folders in the save folder, which will include a modeling file, a results file, etc. ...
I want to know what the specifications of these files are?
Can these output files be the same as the database? Or if they have another standard format ، what it can be?

They can have any format you like if you are saving your own data.
