Why did a "Forms" folder appear in my library? Can I delete it?

I created a library and I noticed a folder titled "Forms" was created as a result. Opening the folder revealed a bunch of links and a word document. Opening these, in turn, showed that the links took me to blank pages and the word document was similarly empty.

I'd rather not have a folder with such content inside my library unless it is essential to some library function.

A few questions:

1. What is the "Forms" folder?


2. 
   

   What does it do?

   
   


3. 
   

   Is it safe to delete?

   
   


4. 
   

   If a user places documents inside it, is it a problem?
