Tree data structure is best suited for this.

1. Design a Tree View Data structure
2. Each Sub folders would be child node of the tree node

In this table how will insert the root directory?
The foreign key constraint will not let you insert an entry with no parent id.

If it is a root directory then values of id and parent_id will be same.
