I am aware that you don't want to remove the innodb tables from
/var/lib/mysql for a linux distro of mysql (I have Ver 14.14). So I used the command
drop database mydb1; drop database mydb2; -- etc
but see that the folders
mydb2 etc. are sill in
/var/lib/mysql, and the .MYD, .MYI and .frm files are there in most cases. Are the database folders safe to manually delete now? I know the innodb files are very sensitive.
