How do I copy hidden files in Linux?

It’s pretty unusual to have a hidden file that doesn’t start with one of those characters. You could use rsync . that will copy the contents of the current directory (including dot files, but not including .. )

Can hidden files be copied?

In Windows ctrl + A will not select hidden files if they are not displayed and therefore they will not be copied. If you copy a whole folder “from the outside” which contains hidden files, the hidden files will also be copied.
