Hi @stingdau1206,

lfs_fs_size returns the number of blocks currently in use. If you multiply this by the block_size the result should be the number of bytes in use.

Because littlefs uses copy-on-write data-structures, the result may sometimes be larger than the actual usage, but it should never be smaller. Hopefully it's still useful for estimating how full the disk is.

Hi @geky thanks for your reply, i'm Looking forward to a more detailed result about disk usage but, after all, it will be ok for my case
