Best Way To Password Protect Excel Files/Folders

[anil099]

I know I can put a password in the excel file itself...is that enough? or can tech savvy people easily overcome that

I'm asking for a work computer/laptop that my employee also uses and I don't want him having access to some excel files

Or is it better to use third party software that locks folders/files?

Thanks

He's a pretty tech savvy/curious guy lol

lock files and folders.
Password protection is ok for most people.
Some people (friends) have passworded before.
the strongest password what ever (takes 10 seconds).
can't edit, but you can view it.
