Should I format Jffs before install Entware?

[ac66ub1]

I reboot twice then mount my jffs by luck.
After that,I reboot and restore to factory,jffs still mounted.
I plan to install entware right now.If I click "Format JFFS partition at next boot",may cause "jffs unmounted" again.
There are some files already in jffs folder as below:
--------------------
admin@RT-AC66U_B1:/jffs# ls
cfg.json nmp_cl_json.js scripts syslog.log
configs nmp_client_list ssl usericon
--------------------

No need just install now.
