Concurrent use of LittelFS and SD

[grescaldani]

Hello, on ESP (both 32 and 8266) I have no problems using LitteFS to read/write to the flash and I have no problems hooking and SD Card adapter and read/write files on the SD. BUT I cannot figure how I can use, in the same sketch, both file systems. For instance to keep some HTML pages on little FS (that is always available) and to write some log files on the sd, that can be removed. Is that possible? Any examples somewhere? Thanks.
