re :Cannot locate composition folder

It's not a folder. It's a toolbar called 'Composition Toolbar'.

In Write window where you compose an email: Can you see the top Menu Bar that has 'File', 'Edit', 'View'...etc ? If yes: 'View' > 'Toolbars' > select 'Composition Toolbar' See image below

In where I compose emails there is no menu at all. Just who you are sending to subject & my email address. No place at all I can click for anything except body text & width what ever they are for.

First you need to get the 'Menu Bar' toolbar visible again.

• Open a new Write message window
• Press the 'Alt' key on your keyboard.

This will show the 'Menu Bar', but now you have to make it permanent.

• 'View' > 'Toolbars' > select 'Menu bar'

This will now allow you to use the instructions I stated in first comment to get the 'Composition Toolbar' enabled again.
