How was this file generated? What does the command file <filename>.msf return? Have you tried head, more and less on the file?

Also, how is the software error tag relevant here?

Hello RamRS,

Thank you so much for your great help!

I think it is a SQLite database.

Thank you again!

If this is related to your prior question then you need to show output of things @RamRS has asked: change *.msf file into excel file

From this, it is apparent that the msf file is a database that can be opened in SQLite. OP should be looking for R packages that can read in SQLite DBs, such as RSQLite: https://db.rstudio.com/databases/sqlite/

Hi @yueli7,

Did you happen to figure out the database schema for these msf files to be used via sqllite?

I'm trying to look at the tables but there are way too many times to manually figure out the schema.

Any pointers are highly appreciated.

Thanks!
