SPIFFS data directory subfolder not converted in prefixed files.

[miky2k]

SPIFFS does not support directories so dir is only a prefix of filename,
if i prepare SPIFFS filesystem in linux (data directory) i cannot prefix files with /somewhere/ (/ is not allowed) but i can create directories , spiffs flash tool does not convert directories name in file prefixes!
