this is redundant with the above. keep one or the other :)

these two includes should not be in the header, but in the CPP file instead. Nothing in the header depends on them :)

The header does depend on them, but they are also included via vfs_api.h, so at most they are redundant. For the same reason they don't need to be included in the .cpp file (because they are included via vfs_api.h which is included via SPIFFS.h).

Whatever, I have removed them from SPIFFS.h, but I haven't added them to SPIFFS.cpp.

FS should be included. vfs_api is a private header.

18 hours ago, you asked me to remove FS.h and FSImpl.h, now you are asking me to add FS.h back in.

If I remove vfs_api.h I will also have to add FSImpl.h back because SPIFFSImpl is declared in SPIFFS.h.

No, I asked about #include "FSImpl.h" and #include "vfs_api.h".
FS.h is the only one that should be included :) I guess a bit of misunderstanding.

This change requires an additional class, SPIFFFSImpl that inherits VFSImpl, which is declared in vfs_api.h, so something is going to need to include vfs_api.h. Currently this class is declared in SPIFFS.h, which is why SPIFFS.h includes vfs_api.h. How would you have me resolve this?

Does this class need to be public? What happens if the declaration goes into the CPP file?

It should be fine if I move it to the CPP file.
