This is mostly a straightforward wrapper around SPIFFS, with a few enhancements:

Metadata caching

Metadata can be updated multiple times while a file is open so for efficiency it is kept in RAM and only written to SPIFFS on close or flush.

Directory emulation

SPIFFS stores all files in a flat format, so directory behaviour is emulated including opendir() and readdir() operations. Overall path length is fixed according to SPIFFS_OBJ_NAME_LEN.

File truncation

Standard IFS truncate() method allows file size to be reduced. This was added to Sming in version 4.
