By mistake I executed this command on Ubuntu 16.04
sudo chmod -R -x * && sudo chmod -R +X *
Now all the folder converted into files, which is not opening.
How can I fix it?
You have removed execution-rights (and thereby access to) all directories and eventually files that where executable.
Start by giving back exec to directories:
find . -type d -exec chmod +x {} \;
If you had any executable programs, then for each of these do:
chmod +x filename
The +xin the commands above gives execute rights to all (user, group and others - the three different access levels in a linux/posix filesystem)). If you for some reason needs to restrict access to only user or user+group you can replace +x with u+x or ug+x to achieve this.

what do you mean "eventually"? Shouldn't OP start by giving
xonly to u? – Zanna♦ Aug 10 '17 at 11:09 -

Perhaps you could investigate which directories should not have
xfor u - I attempted it in my answer here Home files and folders permissions could not be determined – Zanna♦ Aug 10 '17 at 11:21 -
@Zanna .. I think that it is more relevant to identify directories that should ONLY have
xfor u .. but besides that, you are right. – Soren A Aug 10 '17 at 11:29
chmodprobably never ran, sincechmodwould show an error because it couldn't descend into any directories on which it had already set-x. – muru Aug 10 '17 at 8:21
