    @defragster Thanks. Figured it would help with your examples as well. Think I have add a few more notes in though on printing details for directory, memory usage and formatting. Need a break though :)

    Morning all again. I started putting together a readme for LittleFS, https://github.com/mjs513/LittleFS/tree/main, just started so not much there. So if you all have any suggestions let me know.

    @defragster With the combined .h files now you don't use #include <LittleFS_NAND.h>. As a matter of fact it has been deleted in beta11. Wonder if you have an extra copy of LittleFS floating around..
