Cannot create symbolic link inside different folder I use

ln -sF "./Explore" "testExplore"


to create a link to folder Explore in the current directory. And it works. If I click on testExplore I see the content of Explore.

However I want to create a link to Explore at "folder/testExplore"

    ln -sF "./Explore" "./folder/testExplore"


does create the link in the correct folder, but it does not show the contents of the linked folder. what am I missing here?
You must use the full path for both the source and target.  

ln -sF /Users/allan/Desktop/Explore /Users/allan/Desktop/folder/testExplore

Hint:

An easy way to expand out your path (if you are in it already) is to expand the variable PWD (use $PWD to reference it)

ln -sF $PWD/Explore $PWD/folder/testExplore

And if you hit the Tab key after referencing the PWD variable:

ln -sF $PWD Tab  gives you:

ln -SF /Users/allan/Desktop/
