What is a .f90 file?
A .f90 file is a Fortran. This one is a specialist format without an obvious everyday home.
How to open a .f90 file
- The program that created it is by far the most reliable way to open it.
- On Windows, use a hex viewer or the free TrID tool to identify what the file really is.
- On Mac or Linux, running `file yourfile` in the terminal identifies most formats instantly.
The registry records this extension against Fortran, so software from that family is the most likely match.
How to convert a .f90 file
- Identify the file first, then look for an export or Save As option in whatever program can read it.
