help
Zephyr provides several file system types including FatFS and
LittleFS, but it is possible to define additional ones and
register them. A slot is required for each type.
config FILE_SYSTEM_MAX_FILE_NAME
int "Optional override for maximum file name length"
default -1
help
Specify the maximum file name allowed across all enabled file
system types. Zero or a negative value selects the maximum
file name length for enabled in-tree file systems. This
default may be inappropriate when registering an out-of-tree
file system. Selecting a value less than the actual length
supported by a file system may result in memory access
violations.

help
This shell provides basic browsing of the contents of the
file system.
