ROM Hack Everyfile Explorer obj import error

[T0biasCZe]

I am modding MK7 Custom track,when i try to import the obj into EFE in File > Newfrom file > 3ds > CTR graphics,select the obj and write the name,it throws "the given paths format is not supported"
What does it cause ?
Adding the whole error log
