An improvement to this pattern would making the file format known at instantiation, either explicitly or inferred.
gfile = FileWrapper(egridfile) # infers fileformat from suffix and/or contents
# declares the file format -- should it be checked against the suffix and/or contents?
gfile = FileWrapper(egridfile, format="egrid")
This is fairly easy to implement when reading files but some consideration is needed when creating a FileWrapper instance to write a file.
The FileWrapper class has had a few methods to detect file formats but this should likely be something that is generalized on initialization.
For the moment (with a pending PR) to get the file format one must manually collect it, but it can also be proposed:

(The keyword might also be
fformat)
