Is there a way to set password to a folder?

[TurhaN]

Pretty much the title. I want the folder to ask the password when I try to launch it. Is that possible?

There may be no way to do that. I recommend to use Veracrypt.

Maybe possible but if that is advisable is a different question…

FDE should be preferred:
