I'm not an expert in C++, but SPIFFS library (FS.h) defines a namespace called "fs". It should be possible to differenciate class definitions using it.

I found this useful [https://github.com/me-no-dev/Arduino/commit/72c2c3f4e2a0c4de29ce5f946417aed6130748d5]
But now I have to specify what namespace am using:

void readFromSD(String path){
    using sd::File;
    File hFile = SD.open(path);
    ...
}
void readFromFS(String path){
    using fs::File;
    File hFile =  SPIFFS.open(path, "r");
    ...
}

Currently this isn't possible, because both SD and SPIFFS provide a class called File.
There is, however, a suggestion to put SD library into its own namespace (#1524).

Any progress on being able to use SD and SPIFFS at the same time?

maybe this is a work around.

Solution is explained here: #1524 (comment)
Seems to work for me.
